Not long after the spectacular 1977 World Series where Thurman Munson and the Yankees defeated the Dodgers to win the franchise's 21st World Series championship, their first since 1962, Thurman Munson was asked to help promote the Grand Opening of "The Amherst Sport Spot" sporting goods store on Amherst Road in Massillon, OH. On November 19, 1977 from 11:00 to 1:00pm, Thurman Munson was in the store, meeting enthusiasts and signing baseballs for any customer who purchased anything for $10 or more. Our consignor, the ball's original owner, was in the store that very day, spent $10 and went home with undoubtedly the finest single-signed Thurman Munson ball we've ever encountered. Stored away since that November day in 1977, this Official American League (MacPhail) Spalding baseball was signed on the sweet spot by New York Yankee great Thurman Munson on November 19, 1977, in bright blue ink. Ball presents NRMT+, is white as snow and features blue factory stamps that look as new as can be. It truly looks as if its been in a box, squirreled away since 1977. Comes with copy of original advertisement offering a signed baseball with any purchase at the store, PSA LOA and JSA LOA.
