12 card set. These were originally printed on one sheet (we offered an uncut sheet in a previous auction), and you can see the cut lines on several of these. They were intended to be placed on Roy Rogers drink lids. These lack the perforation for the straw hole, have not been cut down to their final disc shape, and (obviously) not actually been attached to a lid. An unusual item that's a must have for oddball Yankee collectors.
