Mini Cup Sticker Set

I posted about the Superman Mini Cups 1979 a few weeks ago. I found the entire mini cup sticker set on sale at eBay earlier. The twelve stickers are from 1979 and feature Superman, Lex Luthor, Wonder Woman, Aquaman, Batman, Robin, Batgirl, Riddler, Joker and Penguin. The mini cups and stickers were found in quarter vending machines.
