Description

I lost a set of rare baseball cards, including a 1952 Mickey Mantle and other vintage cards while I was at the Rochester Flea Market last weekend. I think I may have left them on one of the tables while chatting with a vendor. They are in a black plastic binder. If anyone has seen them, I'd really appreciate any information!
