An Etch A Sketch has a thick, flat gray screen in a red plastic frame. There are two white knobs on the front of the frame in the lower corners. Twisting the knobs moves a stylus that displaces aluminum powder on the back of the screen, leaving a solid line. The knobs create lineographic images. The left control moves the stylus horizontally, and the right one moves it vertically.The Etch A Sketch was introduced near the peak of the Baby Boom on July 12, 1960 for $2.99 (equivalent to $32 in 2024).[2] It went on to sell 600,000 units[2] that year and is one of the best known toys of that era. In 1998, it was inducted into the National Toy Hall of Fame at The Strong, in Rochester, New York. In 2003, the Toy Industry Association named Etch A Sketch one of the 100 most memorable toys of the 20th century.[3] The Etch A Sketch has since sold over 100 million units worldwide.[4]
