This book contain alot of KC blues autos. They were the farm team for the Yanks in the late 40's and 50's when these autos were obtained. I have about 30+ autos in this book. Mantle, Rizzuto, Skowren, Bauer, Siegrest, and alot more. I even have the bat boys autos from 51 when Mantle played for them. Thank god for Old women who were great ball fans. I wish I could have bought more of her collection.
