In my youth I had a Batman Colorforms playset that was similar to the image you see above thanks to Tracy’s Toys. Even if they decided for some reason to manufacture the sets with a glaring error…go ahead and look at the picture, I’ll wait. Did you find it? Yes! They didn’t include the Riddler!
I’ve read that in 1976 the Batman playset was repackaged and reissued…but I remember the colorforms being preset to more action positions, you couldn’t adjust the arms and legs as you wished. I certainly know I never saw a TV commercial that made the Batman Colorforms set look like so much fun!
