Official National League (Giamatti) baseball signed by Dodgers Hall of Fame pitchers Sandy Koufax and Don Drysdale. Both players have signed the ball in blue ink (grading 7/10), with Koufax's signature appearing on the sweet spot and Drysdale's on the side panel directly below. The ball displays light, scattered age toning and is otherwise in Excellent to Mint condition. A PSA hologram label (E60629) is affixed to a side panel, but no corresponding COA accompanies the ball (the ball is listed in PSA's database as "Authentic").
