Abstract
Abstract A film projector toy is described, including a projector casing and a film cassette received by the casing. The film cassette includes a plurality of films movable one relative to another. Indicia representing different portions of a complete, predetermined picture image are illustrated on each film and the films are superimposed in the cassette. The indicia are then projected, for example, on a wall, so as to form the complete picture image. At least one film is then moved relative to the other films so that the indicia are moved, thereby creating a moving picture image.
