Presented is a wonderful addition to any sports collection - a signed baseball from the American League pennant winning New York Yankees, a team of iconic stars that would more than double the total runs scored by the Pittsburgh Pirates in the Series (55-27) and yet be defeated by Pittsburgh by 4 games to 3. How could that possibly occur? The Yankees took each of their wins by blowouts: 16-3, 10-0, and 12-0. The Pirates, on the other hand, won four close games: 5-4, 3-2, 5-2, and 10-9 in Game 7, on the famous walk-off home run by Hall of Famer Bill Mazeroski in the bottom of Inning 9. (20) signatures: Hall of Famers Mickey Mantle and Yogi Berra on the sweet spot. Also, Roger Maris, Casey Stengel (secretarial), Clete Boyer, Bobby Shantz, Bob Turley, Bob Cerv, Duke Maas, Bob Richardson, Kent Hadley, Bill Skowron, John Gabler, Ralph Terry, Hector Lopez, Elston Howard, Frank Crosetti (coach), Gil McDougald, Eli Grba, and Spud Murray (a Yankee batting practice pitcher who was a friend of Mantle and Whitey Ford). The ball is an American League Official Baseball (Joe Cronin) that is EX-MT. The signatures average 7-8/10. Legendary signatures from a legendary team. PSA LOA.
