Abstract

Abstract A foldable display stand made from cardboard or like material having a support stand and a tray portion fixed to the support stand. In collapsed form, the support stand wraps around the tray. The support stand includes two walls which extend upwardly to a ceiling. The ceiling is made of two panels of equal size and foldable upwardly by a common center fold line. One panel of the ceiling is bonded to the bottom of the tray. When erecting the display stand, the two opposite lateral walls, which include vertical foldable center fold lines, are extended by the weight of the tray to the extent that the two panels of the ceiling are arranged in a common plane.
