I'm a little fuzzy on the details, but my Grandfather (he might have had a partner in the deal) created Clink a Links and began producing them in his basement. My mother can remember boxing them up in the evenings. I've got some other photos I'll post later of my Grandmother at a trade show display. The photo I posted was dated 1958. I think he sold the rights to a larger company a few years later which is probably the version you are familiar with. I'll try to dig up some more details.
Wow, who would have thunk that I could find a family member of the creator. Cool stuff- did he create any other toys we might know?
