When collapsed, the support stand is adapted to wrap about at least a portion of the tray. The support stand includes two walls which extend upwardly to what is essentially an openable ceiling. The ceiling comprises two panels which are foldable upwardly from the front and rear wall of the support stand, respectively. At least one panel of the ceiling is bonded to the bottom of the tray. When the display stand is collapsed, the two opposite lateral walls, both of which include vertical foldable center fold lines, are extended so that they overlie one another in a common plane.
