Presented is an ONL (Giles) ball that served as one of the last to see action on the island of Manhattan, inscribed "Last Game 9/29/57" in vintage red ink and autographed by Hans Lobert, Sid Gordon, Hank Thompson, Monte Irvin and Buddy Kerr. This unusual mixture of past and present Giants further serves to authenticate the sphere, as the newspaper notes that many Polo Grounds vets were on hand for the pre-game ceremonies. Ball shows obvious game use and signatures rate 9/10 on average. Pre-certified by PSA/DNA. Auction LOA from James Spence Authentication.
