2012 Panini Prime Cuts, Bob Feller Souvenir Cuts, #'d 82/99. I thought that a serial number of 99 seems a bit high for a cut signature, but I guess Feller signed a good amount of stuff. The back blurb on this card mentions Sandy Koufax.
It is always interesting to read about Bob Feller, a World War II veteran and one of the greatest pitchers of all time, who by all accounts was a level-headed and honest workhorse, gentleman, and all around stand-up dude. Feller was a teammate of the pioneering Larry Doby, the American League's first African-American player. Doby was elected to the Hall of Fame on this date in 1998. I think I will try to acquire a Larry Doby signature so that he and Feller can hang out together in my collection.
