His 2,763 managerial wins are the most of anyone not named Connie Mack. John McGraw signed this Official National League (Heydler) baseall in 6.5 black ink alone on a side panel and it is pretty clean and close to EX condition. Though not officially a single-signed ball, it displays as one as the opposite panel displays two other signatures, and, on another panel stands the signature of naval officer and Medal of Honor recipient, Admiral Richard E. Byrd in 9/10 black ink. Byrd was also an explorer who claimed that his expeditions were the first ever to the North and South Poles. Comes with PSA LOA.
