"Reach Official League" baseball has been boldly signed at the sweet spot by Mack, who was inducted into the Hall of Fame in 1937 and has one of the most storied histories in all of baseball. He stands as the longest-serving manager in MLB history and holds records for total wins/losses/games managed. He managed the Philadelphia Athletics for the club's first 50 seasons of play before retiring following the 1950 season, and was at least part-owner from 1901 to 1954. His five World Series titles remain the third most by any manager. Ball has scattered aging w/two small spots at first letter of Mack's first name, but signature is still bold and sharp. Moderate wear to Reach markings. Fine overall, w/VF signature. Single-signed baseballs signed by Mack are scarce. Comes with Hake's COA and JSA LOA.
