Osso, I have two lovely pictures that I suspect are rare. They are of landscapes and obviously in oils. The signature is by someone named Roberts. On the back is a tag that says: Hand colored gravure. I understand the process of gravure, but I have often wondered about the origin. I don't think that I have ever seen any others quite like them.
Hmm. In some big cities they have days where you can take your item in question to experts to look at. In LA, there is a place called Butterfield's that does that. Or there was. Metropolitan Home magazine used to have a column where you sent a photo; don't know if that is still possible. GWlightwizard knows a lot about art prints, and may have advice about where you could find out.
