Three Brooklyn Dodger Legends are commemorated in this terrific lot. This is how it breaks down: Roy Campanella (post-accident signature) on an official National League (Giamatti) baseball with PSA LOA, Sandy Koufax on an official Major League baseball with MLB hologram, OA hologram and Steiner COA; and Don Drysdale, who signed on the sweet spot of an official National League (White) baseball.
