Joan Rivers gave her comedy work-shop writer collaborator friend Claibe Richardson a boxed puzzle that she had been given by one of her fans. The puzzle was a 24" round RED DOT. When Hub Braden visited New York City, Claibe gave Hub the puzzle to take back to California. Hub gave the puzzle to mutual puzzle fanatic friends Neil Foster, Vern Lanegrasse and Walter Wood, who put the puzzle together. After the puzzle was completed, missing one piece located in the middle of the red dot puzzle, Hub had the Prospect and Talmadge ABC TV studio's carpenter shop glue down the puzzle on to a 24" diameter hard Masonite circle, lacquered for use as a tray. When Joan Rivers made her first and only Hollywood appearance on the ABC TV variety show "The Hollywood Palace," host: Vince Edwards (air show: #3.19, February 5,1966), Hub gave the "red dot puzzle" to Joan, asking, "where's the missing piece".
