Only example known to us. 3.5". Also reads "We Want Cantor On TV." Promotional button for short-lived early TV comedy hour of very popular radio star, singer & actor. 'Banjo Eyes' was also responsible for sponsoring careers of many other entertainers of the day such as Eddie Fisher. Well-made button. One of few nice early TV show buttons and certainly best Eddie Cantor button. White metal back with bar pin has minor wear. Front tiny surface wear in reflected light. Exc., displays Mint. We've had small plastic pin promoting Comedy Theater but this is first as large cello button.
