Tremendous midgrade example of the key card from the 1958 Topps issue, that of Hall of Famer and Yankee superhero Mickey Mantle.  With a sharp image and clean, white borders, some minor surface wear accounts for the grade, as does some light corner wear, particularly at the top left.  Centering is reasonable in an issue known for egregiously off-center cards.  An excellent example of one of Mantle's most popular early cards.
