Dexter Press produced premiums for Coca Cola in 1966 ( 2 team sets ), 1967 ( 229 5 1/2" x 7 1/4" premium set --all MLB teams) and a reduced set of 77 players ( postcard sized ) in 1968. Border less and considered maybe the most attractive sets of the 60's.. Mays is one of the keys to the 1968 set, this one is excellent or better--- scarce and dramatic.... easily out classing the Topps issues from the same period--- free shipping
