I was just watching an episode of "Antiques Roadshow" today, and there was a man on there with a few dozen old cans he found in a ghost mining town out west. One can with a very clear and well-preserved label was for canned tomatoes, and it said Keokuk, Iowa, on the bottom of the label. I can't find anything on this on the Internet. Does anyone out there any any info on this. It was a company that was in operation in the 1800's.
