Is a print from the Ullman Manufacturing Company copyright 1900 Antique Road Show material?
Generally, I would say no. It depends partly on who the artist is and how popular they are. Ullman Manufacturing made LOTS or prints, kind of like what you might find in Wal-Mart today (albeit the older ones are higher quality in many respects). I had an Ullman print from a fairly famous artist that was still working hard at the time the print was made (circa 1900), and I was lucky to get $40 for it, and that may be just because it had a nice period frame…
