Toy Tinkers
Toy Tinkers, also called the Tinker Toy Company, was an Evanston, Illinois toy company. According to the YoYo Wiki it entered yo-yos in the mid-1950s with its Toy-O-Ball series, rewinding yo-yos in round plastic shells made as baseballs, basketballs and footballs. The wiki says it is unclear whether Toy Tinkers made the similar HEP line or the reverse, and a link to the Tinkertoy lineage is not confirmed.
