ABSTRACT:
A picture display device includes a plurality of generally rectangular frames hinged together, edge-to-edge in an endless series. The frames can be folded into an arrangement defining a compact pack from which a pair of frames project in an inverted-V display position. The assembly of frames is detachably mountable to a support device and in a manner in which manual rotational movement of the upwardly projecting pair of frames from the display position back toward the pack automatically raises another pair of frames to the display position.
