Etch A Sketch manufacturer, Ohio Art Company, has published an advert honouring its late inventor, André Cassagnes, who died last month aged 86.
According to the Toy Industry Association, Cassagnes came up with the idea for Etch A Sketch in the late 1950s when he peeled a translucent decal from a light switch plate and found pencil mark images transferred to the opposite face.
The much-loved kids toy was the number one seller in 1960 and more than a million have been sold worldwide since then.
The company's president Larry Killgallon said of the inventor: "Etch A Sketch has brought much success to the Ohio Art Company, and we will be eternally grateful to André for that. His invention brought joy to so many over such a long period of time."
