The exact date is not known. The concept was invented by André Cassagnes in the late 1950s. He first exhibited a prototype in 1957. He took it to a French plastic molding company, which filed a patent on it in 1959 (leaving Cassagnes' name off the patent application). Subsequently, the Ohio Art Company bought the invention and announced the product on July 12, 1960.
