Chaplin's megaphone and clapboard

This megaphone and clapboard, from the collection of Robert Florey, assistant director on Monsieur Verdoux (1947), were sold in a 2004 Christie’s auction. The megaphone is from the early 1930s, but was also used during the filming of The Great Dictator (1940), according to Florey. You can see Charlie using a very similar megaphone, below, on the set of Modern Times (1936).
