Light to moderately toned J.Heydler National League baseball signed on a side panel by New York Giants player and manager John J. McGraw. Autograph is well formed and clearly legible rating 6 out of 10. The ball itself exhibits some general handling/age wear retaining bold Spalding manufacturer's stampings and Heydler facsimile signature stamp. Under magnification, PSA has determined some evidence that an inscription may have been removed. John McGraw was not only a well seasoned player during the late 19th and early 20th centuries but went to become regarded as one of the greatest managerial tacticians in the history of the game. McGraw's raw style of play and difficult personal life fused to create hardened managerial traits which equated to ten National League pennants and three World Championships. He completed his illustrious career with over 2,700 victories and was elected to the Hall of Fame in 1937. By any and all standards, John McGraw is considered to be one of the greatest managers in the history of the game ranking third on the list of all time winningest managers. One of only two examples we have encountered in our 35 years within the hobby. Includes full LOA from PSA/DNA: Ball: VG-EX, Signature: EX-EX/MT
