I found it on an online blog, took the pic and resized it. I had Superman, Batman, Robin, and Joker as a kid, and the Thing Maker was had by an older brother who had both the Superman and Batman molds. He made me PLENTY of Superman figures, and Batman rings from that thing.
I THINK the bad guys all came in one solid color, and all the heroes were painted as you see in the pic, except for Batman and Robin who came painted and a solid color.
Good times, and it being Christmas was a BIG part of the reason I posted the banner.
For what it's worth, the heroes came in both painted and unpainted versions. Note Johnny Thunder's Thunderbolt is one of the villains, apparently because the pitch included material from the issue where the Johnny Thunder of Earth-One turned him against the League.
My data comes from Two Morrows Justice League Companion, in case anyone is curious.
It has photos from the entire line, including the Batman and Aquaman specific sets.
