Issued in approximately 1970 the "Sports Cards for Collectors Old Timer Postcards" issue was a 32-card set of postcard-sized black and white cards bearing a photo of a player on the obverse with room for a message and address info on the reverse. This example of Johnny Mize has been signed by Mize in blue starkly offsetting the dull black and white of the card image. In overall VG/EX condition (though the signature would grade much higher) the piece has been authenticated and encapsulated by SGC Authentic.
