In the 1960's the Topps Company made a series of Trading Cards called COMIC BOOK FOLDEES. These featured various DC Comics Heroes & Villians on trading cards that could be folded to make different scenes. Basically it's a large card with 3 surfaces. The center surface had a picture of the character. The 2 surfaces on either side had preferations to cut so that there would be "flaps" on each side to fold over. The flaps have the head, torso, & legs of different characters that you could mix & match. Look at the picture on the top of the display box, kinda gives you an idea. There were 44 cards to the complete set & these babies are extremely RARE & very sought out by many collectors!
