I made them as well everything from pirates to astronauts , as a kid I loved the Ben Cooper Halloween costumes and still do , as cheap as they were they were fun and symbolized Halloween for several generations.
I still have a batch of them in the boxes , Ape Soldier from Planet of the Apes , Moe from the 3 Stooges , Gumby , etc
I bring them out and decorate with them every Halloween. Lots of Memories in those little boxes of bygone fun
