Magnificent and pristine, this 1960 Pittsburgh Pirates signed ball contains 19 signatures including Roberto Clemente. The official National League (Giles) ball is signed in blue ink by the following members of that championship team: Murtaugh (clubhouse/ secretarial), Clemente, Vernon, Schoefield, Virdon, Oldis, Smith, Giel, Mazeroski, Baker, Skinner, Law, Green, Daniels, Friend, Gibbon, Groat, Haddix, Face and Mazeroski. All of the autographs range from a 9/10 to a 10/10. All of the manufacturer's stampings are bold and beautiful the ball is in overall NRMT condition. This is an outstanding team-signed ball dating from one of the "magic teams" of its era, and from perhaps the greatest season in Pittsburgh Pirates history. LOA from /PSA DNA.
