When the sports memorabilia market blossomed in the 1980s, Mickey Mantle was a hot ticket, and he remained a popular guest on the show circuit until the end of his life in 1995. A small part of the action is preserved, with this dual-signed 1991 Player's Certification contract for an autograph signing of 172 items. Mickey has signed ("9") by means of a blue ballpoint pen, on the line identified as "Signature of Affiant", and his youngest son Danny has signed ("9") on the "Witnessed By" line, also in blue ink. Auction LOA from James Spence/JSA. Opening Bid $150.
