A DeMarco card from the Exhibit issue is normally not worthy of a separate auction lot not even to Mrs. DeMarco but this card is very much the exception to the rule. On occasion in the 1950s the Exhibit Supply Company issued its sports cards with postcard backs. PC backs are known in its football and baseball issues and bring substantial premiums above their blank-backed counterparts they have sold for ten times or more even for common players. Postcard-backed boxing Exhibits are virtually impossible to locate. We can recall only a few of them ever surfacing and the one offered here would make a fine addition to an advanced type card collection.
