Craft set:Abacus Tinker

In addition to Tinkertoy sets, The Toy Tinkers of Evanston offered several other products that reinforced the company's commitment to making toys that encouraged playfulness, youthfulness, exploration, and education. By the late 1920s, the company introduced the Abacus Tinker, a counting toy made of 165 colored beads on 11 metal rods. The beads could be removed from the rods and rearranged in any pattern imaginable. The Toy Tinkers offered the Abacus Tinker for about two years in 1929 and 1930.
