Abstract: A display that can be expanded from a collapsed position for storage and transport to an expanded position for free-standing operation and use. A spinal member is disposed between front and back panels such that in the collapsed position, the spinal member maintains the two panels substantially adjacent one another in a generally two-dimensional shape. Upon movement of at least a portion of the spinal member relative to the panels, parts of the spinal member bias the panels apart from one another to form an expanded, three-dimensional shape. This shape provides a sufficient footprint of the display relative to its height that the display can be free-standing. The cooperative relationship between the spinal member and the panels is such that no rubber bands or related elastic devices are required to maintain the display in the expanded position.

Abstract: A portable display which comprises a front panel, a back panel, opposed side panels extending between the front and back panels, a bottom panel assembly consisting of four bottom flaps each connected to one of the front, back and opposed side panels, and, top, bottom and intermediate shelves vertically spaced along the back and side panels. The bottom flaps of the base assembly are foldable into a closed position to form a seat which mounts a wheel assembly including a mounting block or axle carrying wheels at either end. The back panel is provided with a handle for moving the display from one location to another, and such handle is formed with slots to receive a header containing advertising for the products being sold.
