Art forgery
Encyclopedia
Art forgery is the creation of works of art
which are falsely attributed to other, usually more famous, artists. Art forgery can be extremely lucrative, but modern dating and analysis techniques have made the identification of forged artwork much simpler.
sculptors produced copies of Greek
sculptures. Presumably the contemporary buyers knew that they were not genuine. During the classical period art was generally created for historical reference, religious inspiration, or simply aesthetic enjoyment. The identity of the artist was often of little importance to the buyer.
During the Renaissance
, many painters took on apprentices who studied painting techniques by copying the works and style of the master. As a payment for the training, the master would then sell these works. This practice was generally considered a tribute, not forgery, although some of these copies have later erroneously been attributed to the master.
Following the Renaissance, a redistribution of the world’s wealth created a fierce demand for art among the newly prosperous middle class. Near the end of the 14th century, Roman statues were unearthed in Italy, intensifying the populace’s interest in antiquities
, and leading to a sharp increase in the value of these objects. This upsurge soon extended to contemporary
and recently deceased artists. Art had become a commercial commodity
, and the monetary value of the artwork came to depend on the identity of the artist. To identify their works, painters began to mark them. These marks later evolved into signatures. As the demand for certain artwork began to exceed the supply, fraudulent marks and signatures began to appear on the open market.
During the 16th century imitators of Albrecht Dürer
's style of printmaking added signatures to them to increase the value of their prints. In his engraving of the Virgin, Durer added the inscription "Be cursed, plunderers and imitators of the work and talent of others". Even extremely famous artists created forgeries. In 1496, Michelangelo
made a sleeping Cupid
figure and treated it with acidic earth to make it seem ancient. He then sold it to a dealer, Baldassare del Milanese, who in turn sold it to Cardinal Riario of San Giorgio
who later learned of the fraud and demanded his money back. However Michelangelo was permitted to keep his share of the money.
The 20th century art market has favored artists such as Salvador Dalí
, Pablo Picasso
, Klee
and Matisse and works by these artists have commonly been targets of forgery. These forgeries are typically sold to art galleries
and auction
houses who cater to the tastes of art and antiquities collectors
.
Copies, replicas, reproductions and pastiche
s are often legitimate works, and the distinction between a legitimate reproduction and deliberate forgery is blurred. For example, Guy Hain
used original molds to reproduce several of Auguste Rodin
's sculptures. However, when Hain then signed the reproductions with the name of Rodin's original foundry
, the works became deliberate forgeries.
which had hung in the Nuremberg
Town Hall since the sixteenth century, was loaned to Abraham Küffner. The painter made a copy of the original and returned the copy in place of the original. The forgery was discovered in 1805, when the original came up for auction and was purchased for the royal collection.
Although many art forgers reproduce works solely for money, some have claimed that they have created forgeries to expose the credulity and snobbishness of the art world. Essentially the artists claim, usually after they have been caught, that they have performed only "hoax
es of exposure".
Some exposed forgers have later sold their reproductions honestly, by attributing them as copies, and some have actually gained enough notoriety to become famous in their own right. Forgeries painted by the late Elmyr de Hory
, featured in the film F for Fake
directed by Orson Welles
, have become so valuable that forged de Horys have appeared on the market.
A peculiar case was that of the artist Han van Meegeren
who became famous by creating "the finest Vermeer ever" and exposing that feat eight years later in 1945. His own work became valuable as well, which in turn attracted other forgers. One of these forgers was his son Jacques van Meegeren
who was in the unique position to write certificates stating that a particular piece of art that he was offering "was created by his father, Han van Meegeren".
Forgers usually copy works by deceased artists, but a small number imitate living artists. In May 2004, Norwegian painter Kjell Nupen noticed that the Kristianstad
gallery was selling unauthorized, signed copies of his work.
s and auction houses have been overly eager, by accepting forgeries as genuine, and selling them quickly, to turn a profit. If a dealer finds the work is a forgery, he may quietly withdraw the piece and return it to its previous owner—giving the forger an opportunity to sell it elsewhere.
Some forgers have created false paper trails relating to a piece, in order to make the work appear genuine. British art dealer John Drewe
created false documents of provenance
for works forged by his partner John Myatt
, and even inserted pictures of forgeries into the archives of prominent art institutions. Experts and institutions may also be reluctant to admit their own fallibility. Art historian Thomas Hoving estimates that various types of forged art comprise up to 40% of the art market.
s, in an attempt to claim that the forged work is a slightly different copy, or a previous version of a more famous work. To detect the work of a skilled forger, investigators must rely on other methods.
While attempting to authenticate artwork, experts will also determine the piece’s provenance
. If the item has no paper trail, it is more likely to be a forgery. Other techniques forgers use which might indicate that a painting is not authentic include:
More recently, magnetic signatures used in the ink
of bank notes are becoming popular for authentication of artworks.
of digital image
s of paintings is a new method that that has recently been used to detect forgeries. Using a technique called wavelet
decomposition, a picture is broken down into a collection of more basic images called sub-bands. These sub-bands are analyzed to determine textures, assigning a frequency
to each sub-band. The broad strokes of a surface such as a blue sky would show up as mostly low frequency sub-bands whereas the fine strokes in blades of grass would produce high frequency sub-bands.
A group of thirteen drawings attributed to Pieter Brueghel the Elder
was tested using the wavelet decomposition method. Five of the drawings were known to be imitations. The analysis was able to correctly identify the five forged paintings. The method was also used on the painting Virgin and Child with Saints, created in the studios of Pietro Perugino
. Historians have long suspected that Perugino painted only a portion of the work. The wavelet decomposition method identified that at least four different artists had worked on the painting.
s, writing books about paintings, sculpture, and other art forms. Communication amongst the different specialties was poor, and they often made mistakes when authenticating pieces. While many books and art catalogues were published prior to 1900, many were not widely circulated, and often did not contain information about contemporary artwork. In addition, these specialists lacked many of the important technological means that experts use to authenticate art today.
The fact that experts do not always agree on the authenticity of a particular item makes the matter of provenance
more complex. Some artists have even accepted copies as their own work - Picasso once said that he "would sign a very good forgery". Jean Corot painted over 700 works, but also signed copies made by others in his name, because he felt honored to be copied. Occasionally work that has previously been declared a forgery is later accepted as genuine; Vermeer's Young Woman Seated at the Virginals had been regarded as a forgery from 1947 until March, 2004, when it was finally declared genuine, although some experts still disagree.
At times restoration
of a piece is so extensive that the original is essentially replaced when new materials are used to supplement older ones. An art restorer may also add or remove details on a painting, in an attempt to make the painting more saleable on the contemporary art market. This, however, is not a modern phenomenon - historical painters often "retouched" other artist's works by repainting some of the background or details.
Many forgeries still escape detection; Han van Meegeren
, possibly the most famous forger of the 20th century, used historical canvas
ses for his Vermeer forgeries and created his own pigments to ensure that they were authentic. He confessed to creating the forgeries only after he was charged with treason
, an offense which carried the death penalty. So masterful were his forgeries that van Meegeren was forced to create another "Vermeer" while under police guard, to prove himself innocent of the treason charges.
A recent, thought-provoking instance of potential art forgery involves the Getty kouros
, the authenticity of which has not been resolved. The Getty Kouros was offered, along with seven other pieces, to The J. Paul Getty Museum
in Malibu, California in the spring of 1983. For the next twelve years art historians, conservators, and archeologists studied the Kouros, scientific tests were performed and showed that the surface could not have been created artificially. However, when several of the other pieces offered with the Kouros were shown to be forgeries, its authenticity was again questioned. In May 1992, the Kouros was displayed in Athens, Greece, at an international conference, called to determine its authenticity. The conference failed to solve the problem; while most art historians and archeologists denounced it, the scientists present believed the statue to be authentic. To this day, the Getty Kouros' authenticity remains a mystery and the statue is displayed with the date: "Greek, 530 B.C. or modern forgery".
and Ansel Adams
became frequent targets of forgery. The detection of forged photography is particularly difficult, as experts must be able to tell the difference between originals and reprints.
In the case of photographer Man Ray print production was often poorly managed during his lifetime, and many of his negatives were stolen by people who had access to his studio. The possession of the photo-negatives would allow a forger to print an unlimited number of fake prints, which he could then pass off as original. Fake prints would be nearly indistinguishable from originals, if the same photographic paper was used. Since unused photographic paper has a short (2–5 years) useful life, and the composition of photographic paper was frequently changed, the fakes would have had to be produced not long after the originals.
Further complicating matters, following Man Ray's death, control of printing copyrights fell to his widow, Juliet Man Ray, and her brother, who approved production of a large number of prints that Man Ray himself had earlier rejected. While these reprints are of limited value, the originals, printed during Man Ray's lifetime, have skyrocketed in value, leading many forgers to alter the reprints, so that they appear to be original.
For example, federal prosecutions have been successful using generalized criminal statutes, including the Racketeer Influenced and Corrupt Organizations Act
("RICO"). A successful RICO charge was brought against a family which had sold counterfeit prints purportedly by Chagall, Miro, and Dali. The defendants were also found guilty of other federal crimes including conspiracy to defraud, money laundering
, and postal fraud. Federal prosecutors are also able to prosecute forgers using the federal wire fraud
or mail fraud statutes where the defendants used such communications.
However, federal criminal prosecutions against art forgers are seldom brought due in part to high evidentiary burdens and competing law enforcement priorities. For example internet art frauds now appear in the federal courts' rulings that one may study in the PACER court records. Some frauds are done on the internet on a popular auction websites. Traces are readily available to see the full extent of the frauds from a forensic standpoint or even basic due diligence of professionals who may research matters including sources of PACER / enforcing authority records and on the internet.
Prosecution is also possible under state criminal laws, such as prohibitions against criminal fraud, or against the simulation of personal signatures. However, in order to trigger criminal liability under states’ laws, the government must prove that the defendant had intent to defraud. The evidentiary burden, as in all criminal prosecutions, is high.
Art forgery may also be subject to civil sanctions. The Federal Trade Commission
, for example, has used the FTC Act to combat an array of unfair trade practices in the art market. An FTC Act case was successfully brought against a purveyor of fake Dali prints in FTC v. Magui Publishers, Inc., who was permanently enjoined from fraudulent activity and ordered to restore their illegal profits. In that case, the defendant had collected millions of dollars from his sale of forged prints.
At the state level, art forgery may constitute a species of fraud, material misrepresentation, or breach of contract. The Uniform Commercial Code provides contractually-based relief to duped buyers based on warranties of authenticity. The predominant civil theory to address art forgery remains civil fraud. When substantiating a civil fraud claim, the plaintiff is generally required to prove that the defendant falsely represented a material fact, that this representation was made with intent to deceive, that the plaintiff reasonably relied on the representation, and the representation resulted in damages to the plaintiff.
Some legal experts have recommended strengthening existing intellectual property laws to address the growing problem of art forgeries proliferating in the mass market. They argue that the existing legal regime is ineffective in combating this growing trend.

Methods of detection
The most obvious forgeries are revealed as clumsy copies of previous art. A forger may try to create a "new" work by combining the elements of more than one work. The forger may omit details typical to the artist they are trying to imitate, or add anachronismAnachronism

s, in an attempt to claim that the forged work is a slightly different copy, or a previous version of a more famous work. To detect the work of a skilled forger, investigators must rely on other methods.
Technique of examination
Often a thorough examination (sometimes referred to as Morellian Analysis). of the piece is enough to determine authenticity. For example, a sculpture may have been created obviously with modern methods and tools. Some forgers have used artistic methods inconsistent with those of the original artists, such as incorrect characteristic brushwork, perspective, preferred themes or techniques, or have used colors that were not available during the artist’s lifetime to create the painting. Some forgers have dipped pieces in chemicals to "age" them and some have even tried to imitate worm marks by drilling holes into objects (See image, right).While attempting to authenticate artwork, experts will also determine the piece’s provenance

. If the item has no paper trail, it is more likely to be a forgery. Other techniques forgers use which might indicate that a painting is not authentic include:
- Frames, either new or old, that have been altered in order to make forged paintings look more genuine.
- To hide inconsistencies or manipulations, forgers will sometimes glue paper, either new or old, to a painting's back, or cut a forged painting from its original size.
- Recently added labels or artist listings, onto unsigned works of art, unless these labels are as old as the art itself, suspicion should be aroused.
- While art restorers legitimately use new stretcher bars when the old bars have worn, new stretcher bars on old canvases might be an indication that a forger is attempting to alter the painting’s identity.
- Old nail holes or mounting marks on the back of a piece, might indicate that a painting has been removed from its frame, doctored and then replaced into either its original frame or different frame.
- Signatures, on paintings or graphics, that look inconsistent with the art itself (either fresher, bolder, etc.).
- Unsigned work that a dealer has "heard" is by a particular artist.

Problems with authentication
Art specialists, whom we now refer to as experts, began to surface in the art world during the late 1850s. At that time they were usually historians or museum curatorCurator

s, writing books about paintings, sculpture, and other art forms. Communication amongst the different specialties was poor, and they often made mistakes when authenticating pieces. While many books and art catalogues were published prior to 1900, many were not widely circulated, and often did not contain information about contemporary artwork. In addition, these specialists lacked many of the important technological means that experts use to authenticate art today.
The fact that experts do not always agree on the authenticity of a particular item makes the matter of provenance
Provenance
Provenance, from the French provenir, "to come from", refers to the chronology of the ownership or location of an historical object. The term was originally mostly used for works of art, but is now used in similar senses in a wide range of fields, including science and computing...
more complex. Some artists have even accepted copies as their own work - Picasso once said that he "would sign a very good forgery". Jean Corot painted over 700 works, but also signed copies made by others in his name, because he felt honored to be copied. Occasionally work that has previously been declared a forgery is later accepted as genuine; Vermeer's Young Woman Seated at the Virginals had been regarded as a forgery from 1947 until March, 2004, when it was finally declared genuine, although some experts still disagree.

of a piece is so extensive that the original is essentially replaced when new materials are used to supplement older ones. An art restorer may also add or remove details on a painting, in an attempt to make the painting more saleable on the contemporary art market. This, however, is not a modern phenomenon - historical painters often "retouched" other artist's works by repainting some of the background or details.

A recent, thought-provoking instance of potential art forgery involves the Getty kouros
Getty kouros
The Getty kouros is an over-life-sized statue in the form of a late archaic Greek kouros. The dolomitic marble sculpture was bought by the J. Paul Getty Museum, Malibu, California, in 1985 for $7 million and first exhibited there in October 1986....

in Malibu, California in the spring of 1983. For the next twelve years art historians, conservators, and archeologists studied the Kouros, scientific tests were performed and showed that the surface could not have been created artificially. However, when several of the other pieces offered with the Kouros were shown to be forgeries, its authenticity was again questioned. In May 1992, the Kouros was displayed in Athens, Greece, at an international conference, called to determine its authenticity. The conference failed to solve the problem; while most art historians and archeologists denounced it, the scientists present believed the statue to be authentic. To this day, the Getty Kouros' authenticity remains a mystery and the statue is displayed with the date: "Greek, 530 B.C. or modern forgery".
Photographic forgery
Recently, photographs have become the target of forgers, and as the market value of these works increase, so will forgery continue. Following their deaths, works by Man RayMan Ray

became frequent targets of forgery. The detection of forged photography is particularly difficult, as experts must be able to tell the difference between originals and reprints.
In the case of photographer Man Ray print production was often poorly managed during his lifetime, and many of his negatives were stolen by people who had access to his studio. The possession of the photo-negatives would allow a forger to print an unlimited number of fake prints, which he could then pass off as original. Fake prints would be nearly indistinguishable from originals, if the same photographic paper was used. Since unused photographic paper has a short (2–5 years) useful life, and the composition of photographic paper was frequently changed, the fakes would have had to be produced not long after the originals.
Further complicating matters, following Man Ray's death, control of printing copyrights fell to his widow, Juliet Man Ray, and her brother, who approved production of a large number of prints that Man Ray himself had earlier rejected. While these reprints are of limited value, the originals, printed during Man Ray's lifetime, have skyrocketed in value, leading many forgers to alter the reprints, so that they appear to be original.
Legal issues
In the United States, criminal prosecutions of art forgers are possible under federal, state and/or local laws.For example, federal prosecutions have been successful using generalized criminal statutes, including the Racketeer Influenced and Corrupt Organizations Act
Racketeer Influenced and Corrupt Organizations Act

("RICO"). A successful RICO charge was brought against a family which had sold counterfeit prints purportedly by Chagall, Miro, and Dali. The defendants were also found guilty of other federal crimes including conspiracy to defraud, money laundering

Wire fraud
Mail and wire fraud is a federal crime in the United States. Together, 18 U.S.C. §§ 1341, 1343, and 1346 reach any fraudulent scheme or artifice to intentionally deprive another of property or honest services with a nexus to mail or wire communication....
or mail fraud statutes where the defendants used such communications.
However, federal criminal prosecutions against art forgers are seldom brought due in part to high evidentiary burdens and competing law enforcement priorities. For example internet art frauds now appear in the federal courts' rulings that one may study in the PACER court records. Some frauds are done on the internet on a popular auction websites. Traces are readily available to see the full extent of the frauds from a forensic standpoint or even basic due diligence of professionals who may research matters including sources of PACER / enforcing authority records and on the internet.
Prosecution is also possible under state criminal laws, such as prohibitions against criminal fraud, or against the simulation of personal signatures. However, in order to trigger criminal liability under states’ laws, the government must prove that the defendant had intent to defraud. The evidentiary burden, as in all criminal prosecutions, is high.
Art forgery may also be subject to civil sanctions. The Federal Trade Commission
Federal Trade Commission
The Federal Trade Commission is an independent agency of the United States government, established in 1914 by the Federal Trade Commission Act...
, for example, has used the FTC Act to combat an array of unfair trade practices in the art market. An FTC Act case was successfully brought against a purveyor of fake Dali prints in FTC v. Magui Publishers, Inc., who was permanently enjoined from fraudulent activity and ordered to restore their illegal profits. In that case, the defendant had collected millions of dollars from his sale of forged prints.
At the state level, art forgery may constitute a species of fraud, material misrepresentation, or breach of contract. The Uniform Commercial Code provides contractually-based relief to duped buyers based on warranties of authenticity. The predominant civil theory to address art forgery remains civil fraud. When substantiating a civil fraud claim, the plaintiff is generally required to prove that the defendant falsely represented a material fact, that this representation was made with intent to deceive, that the plaintiff reasonably relied on the representation, and the representation resulted in damages to the plaintiff.
Some legal experts have recommended strengthening existing intellectual property laws to address the growing problem of art forgeries proliferating in the mass market. They argue that the existing legal regime is ineffective in combating this growing trend.
