I have a question about two back-to-back photos of famous paintings. The photos are on a double sided matte and the artists names and the subjects are on the captions. The matteis all one piece and cannot be removed without tearing it in half. My question is how can I find out if these photos are actually vintage photos or worthless prints. Does anyone know when these types of mattes and photos were made. One of the photos was on the cover of the New York Metropolitan Museum of Art Journal in the 20's. Also does anyone know how much they might be worth on Ebay.
Thanks ahead of time for the information,
