1940 Leader Novelty R146 SUPERMAN #20 Through Granite Walls SGC 1 RARE RC POP 1 For Sale

This is an EXTREMELY RARE Superman rookie card. This was released before the 1940 GUM INC. Superman set. These cards were on a box that a toy came in and were perforated. How many of these actually exist still??? If you do a little research you will see that there’s only been a few sales of these types of cards. You can find the box coupon listed on but finding one of the cards is almost impossible. This is a BLUE CHIP investment card!!!!!! There was a sale a few weeks ago on of one of these cards in nowhere as nice of condition as far as color and shape and it went for over 20k in sale. If you have any questions, please feel free to reach out.
