The Etch A Sketch was invented in 1959 by Arthur Granjean and introduced commercially by the Ohio Art Company (Bryan, Ohio) in the 1960s. Granjean originally called it "The Magic Screen." There are a few practicing artists who use the Etch A Sketch to produce professional lineographic work. Most artists make their work permanent by removing the aluminum powder. This is done either by drilling holes in the bottom of the toy or by removing the entire plastic backing. It is then resealed as a semi-permanent, shake-resistant piece of art.
