These kits by Aurora, Addar and AMT pretty much sum up the early seventies for me, Superheroes, Planet of the Apes and Star Trek. I had a lot of these even though I really couldn't build or paint them worth a damn. The Aurora Superhero kits became impromptu action figures when I didn't have the mego figure.
In fact, my dad sold the Aurora Superhero kits, the picture below is a shot from his showroom circa 1975. Click here to see more.
