A very rare collectible, and oh so cute, this child's tee shirt celebrating Yankee stars Mickey Mantle and Roger Maris has its roots circa 1962, when the "M&M Boys" were a popular duo, each an American League MVP (Maris '61, and Mantle '62). Tag on back of neck gives size at 14, and the few stains (the most prominent smallish on the bottom front, and some speckles here and some slight smudges there) charmingly present an item having had some real use by a toddler. Screened on the front, both Yankee heroes are illustrated, each at bat and each a head bust, with their facsimile signatures. By Uni-Wear Inc. Endearing, adorable, and in EX condition.
