One year after the legendary 1927 Yankees staked their claim as one of the most dominant teams in the sport's history, the '28 Yanks repeated as World Champs, winning 101 games and sweeping the St. Louis Cardinals in the Fall Classic. Thirteen members of the 1928 World Champion Bronx Bombers signed this Official National League baseball, including: Babe Ruth, Lou Gehrig, Tony Lazzeri, John Grabowski, Earle Combs, Joe Dugan, Ben Paschal, Herb Pennock, Bob Muesel, Tom Zachary, Wilcy Moore, George Pipgras and Hank Johnson. Ruth's signature is on the sweet spot and grades an 8/10. There are no clubhouse signatures on this ball, and it comes with PSA LOA.
