An amusement device has an image carrying substrate with a corrugated surface with a transverse mirror at a rear end and is marked with first and second sets of strip-like image fragments forming, respectively, first and second composite image components. Image fragments of the second set are both differently shaped, laterally inverted and arranged alternately along the image surface relative to image fragments of the first set so that the corrugations selectively expose image fragments of the first and second sets to the front, away from the reflecting surface, and to the rear, for reflection in the reflecting surface, so that the image fragments of first and second sets combine to form first and second image components, respectively, seen by viewing, simultaneously, directly from the front and by reflection so that first and second image components combine to provide a continuous composite image not readily predicted by a casual spectator.
