"Super Adventure" colorforms indeed... while the logo was definitely based on Superman's logo, it can't be any coincidence that the heroes on the box are the core Super Friends characters! It looks like at this point in Colorforms history, they were experimenting with some full-color pieces along with the single-colored plastic with black ink pieces.
And here's a classic Super Friends coloring book, which I'd love to track down an affordable copy of some day, so I can share the pages here or on the Random Acts of Geekery! To bad Superman's just represented in a head shot here.
I have been a Navy journalist, word processor, graphic designer, medical assisting student, cook, and truck driver, and am currently an eBay seller as well as an employee at a big retail store. I have been and always will be into comics, sf, tv, cartoons, monsters, oldies rock, and lots of other stuff.

Please join me every day at the Fortress of Solitude Trophy room as I present photos of all sorts of Superman collectibles, from toys to games to puzzles to original comic book art and more! I am not offering any of these items for sale - all photos have come from eBay auctions of the past.
