Official American League (Harridge) ball signed by Hall of Fame manager Connie Mack. PSA has graded the ball VG-EX 4 overall, with both the signature and ball receiving identical individual grades of VG-EX 4. Mack's signature has been scripted in black fountain pen across the sweet spot. This ball dates to the 1940-42 manufacturing period, indicating that it was almost certainly signed during Mack's long managerial tenure with the Philadelphia Athletics. The ball is lightly toned and displays a few minor abrasions and blemishes. Full LOA from PSA.
