I am looking trying to find a picture of a toy I had when I was a kid back in the early 60's. If I remember correctly, I think it was called a "Wall Walker." I'm sure there were different themes, but the one I remember consisted of a little spaceman who carried his round "ship" on his back. Inside this sphere were four suction cups on an axle that had a spring on it. You would pull a ring/string which would tighten up the spring inside. Then, you could stick the toy to a window or other smooth surface and it would "walk" up it! Any help?
