While known to the hobby as "Leaf" cards, this set of 144 carries the copyright of Sports Novelties Inc., Chicago. Cards were sold in nickel was packs with a marble, rather than a piece of bubble gum. the second half of the set, #73-144, are quite scarce. In the late 1990s, a large group of high-number wax packs - in excess of 4,000 cards - was added to the surviving supply. The Aparicio has been graded NM by PSA.
