Kenner Spirograph (1972)
Wikipedia tells us that –
Spirograph is a geometric drawing device that produces mathematical roulette curves of the variety technically known as hypotrochoids and epitrochoids. The well-known toy version was developed by British engineer Denys Fisher and first sold in 1965. […] US distribution rights were acquired by Kenner, Inc., which introduced it to the United States market in 1966 and promoted it as a creative children’s toy. Kenner later introduced Spirotot, Magnetic Spirograph, Spiroman, and various refill sets.
The product line launched in 1972/1973 features Teruoki Yagi’s Yagi Double as the primary typeface on the boxes and manual covers.
