Rawlings model "MM9" youth baseball glove, signed by Mantle on the exterior thumb. Mantle's signature has been boldly scripted in blue marker and grades 10/10. This glove, which features a "Mickey Mantle Triple Crown Winner" stamping in the pocket, was available for retail purchase from the late 1950s to the late 1960s, but the offered example appears to be an early model, dating to circa 1959. The glove displays moderate wear commensurate with its former use, including the name of a former owner crossed out on the exterior pinky. All the lacing remains intact and the pocket stampings remain bold and legible. Full LOA from JSA.
