They Call Him Dandy Dean -- Dandy Dean, beau brummell of the circus, four years old and captain of Billy smart's chimpanzee billiard team. They all take their cue from me, so with brush and comb I make sure there isn't a hair cut of place.... Dandy Dean's really a star chimp performer, with a speciality in somersaults. Off-duty, as well as being a Dandy, he's also foster-father to a baby chimp... The latest addition to the troupe. March 14, 1955. (Photo by Paul Popper Ltd.).
