1945 Mexican League card of Negro Leaguer Carlos Colas. Some cards from this set have been appearing on eBay lately, but what I haven't seen yet are any of the biography booklets that go with them. I've only ever had one album from this set. I bought it about 17 years ago and have looked for another ever since. I've only known of one other album, and that's what the current cards are eBay are from. In my album, many of the players had these little booklets that folded open and contained a biography of the player. About a third of the players had booklets in my album. It's possible that the second album didn't have any booklets in it. I've never seen any cards or booklets from this set other than mine or the ones listed on eBay over the past few months. The cards and booklets each measure about 1 7/8" by 2 3/4". That's for the booklets when folded. This is a great set of color cards that rarely surface. And this is the first time I'm aware of that an individual player booklet has ever been offered for sale, either public or private.
