Abstract of the Disclosure A sign in which multiple scenes are present- ed in sequence is comprised of a plurality of juxta- posed rotationally driven display units that are as- sembled with triangularly-shaped hollow sleeves whose side panels are constituted by transparencies on each of which there is a portion of a different complete scene. There are adapters on the upper and lower ends of the display units which have bushings for allowing the juxtaposed display units to be journaled for rota- tion on a stationary light transmissive tubes that serves as axles. The tubes are retained at their low- er ends in a row of equally spaced apart and collinear bores and they are retained at their upper ends by a plate which also has a corresponding row of bores that provide for stabilizing the upper ends of the tubes and for maintaining them in perfect alignment and spacing. The units are driven rotationally in syn- chronism by means of an electric motor that provides the power input to mechanical elements which interlock all of the display units mechanically to assure that they rotate in and remain in synchronism such that when corresponding panels of the display units, which panels each represent a portion of a scene, are rotat- ed into coplanar and stationary position the scene is formed for visualization.
