In the realm of American sports, there is no honor so grand as that of having your uniform number retired and your plaque displayed at Yankee Stadium’s sacred Monument Park. For Hall of Famer Mickey Mantle, it was admittedly the biggest thrill of his career, as he followed Gehrig, Ruth and DiMaggio with those prestigious honors on June 8, 1969. Issued at Yankee Stadium that afternoon, this four-page souvenir program is autographed by its heralded subject. Measuring 8x10”, the front cover features a pinstripe theme with Mantle’s number “7” and the printed title: “A Day To Remember.” Near the top, Mantle has signed in blue marker (“10” strength). The piece remains crisp and crease-free and is accompanied by a full photo LOA from PSA/DNA.
