Collectors often describe the 1953 Bowman Color Pee Wee Reese as one of the prettiest cards ever made. And there’s just a single Gem Mt 10 in PSA’s Pop Report. I ran across it in a Mastro Fine Sports Auctions catalog from May 2000.
Would this card be a “10” today? Who knows? Judging the card’s condition from a small catalog photo is tough. But they wrote that the card has a very faint rough cut along the top and bottom edges and said the image is centered at 55/45.
