Two different designs are featured in these rare lithoed tabs (similar to pins except that metal tabs are used to attach them instead of pin-backs), both featuring portraits of Willie Mays wearing a San Francisco Giants cap. These unusual items were issued with packages of Armour meat in 1958. One shows Mays inside a circle flanked by two baseballs (approx. 2" wide and 1 1/2" high); the other shows him inside a baseball diamond (approx. 1 1/2" wide and 2 1/4 " high). Both are NRMT.
