The W573 are black and white strip card versions of the 1922 E120 set produced by the American Caramel company. The front of these cards are the same design and player pictures as the E120 set. These cards measure 2-1/6 x 3-3/8 (inches) but sizes can vary because these cards were hand cut from horizontal strips of 10 cards. The backs of these cards were originally blank but can be found with STAMPED advertising.
