OAL (Brown) baseball is signed by the 1961 World Champion New York Yankees team at a 1989 reunion. Thirty-three blue ballpoint autographs include Mantle and Houk on the sweet spot surrounded by Berra, Ford, Terry, Turley, Richardson, Skowron, Boyer, Downing, and Sain. Baseball is close to NRMT while the signatures are 8/10. Full LOA from PSA/DNA.
