SuperFolder Stingray

I found these in my grandparents’ basement. They are all from the 70s and early 80s. My favorite one is Chewbacca; he is an original from 1977.
People have told me I should sell these, but as they were played with by my dad and his brothers for years, they aren’t in the best condition. Also, I like them lol. Usually they live on a bookshelf, but I moved them to a chair for a better by (so Rhondella won’t get mad at me)
