ABSTRACT:
An advertising display is convertible between an expanded display configuration and a collapsed configuration for storage and transportation. The display includes a cylindrical tube with generally circular end walls attached to the inner surface of the tube adjacent the top and bottom edges thereof. A center post is secured at a top end to the center of the top end wall and projects through the tube to extend therefrom through a center hole in the bottom end wall. The expanded display is rotatable about the tube by an electric motor mounted within the tube and coupled to the top end wall. The motor is powered by batteries also positioned within the post. The tube has diametrically opposed longitudinal fold lines extending between the top and bottom edges thereof to permit it to be collapsed to a storage and transportation configuration when not in use. Parallel transverse fold lines on each circular end wall enables them to fold inwardly within the tube when it is collapsed. Furthermore, holes within each end wall permit the post of another similarly collapsed display to be inserted therethrough to nest the collapsed displays of the present invention for more compact and convenient storage or transportation.
