TripleSSS Sportscards bought the 1957 Topps "Lionel Carter" set from a Mastro Auction last year. They sold a group of them to sgcman and I was able to get a few of them. The remainder of the set has suffered a different fate that I won't mention here.
Matt PM me or email me at firstname.lastname@example.org. I would like hear about the rest of them.
