The 1961 season witnessed one of the most amazing performances in all of baseball as Yankees teammates Mickey Mantle and Roger Maris went head-to-head for the all-time, single-season homerun record. The NY Yankees are popularized in modern times as the greatest baseball team ever. This ball completes any 1961 Yankee collection! This National League crew were the umpires at Crosley Field when the Yankees captured Game 5 and became World Champions, thus signed on a Warren Giles Official National League ball when they would have all appeared together. Signed by: Vinnie Smith, Ken Burkhart, Ernie Stewart & Frank Walsh in blue inks. Incredible condition! In our opinion it rates a 9/10. JSA Letter of Authenticity. Domestic shipping - $12.00
