An article adapted to be erected to form a shelf which may be attached to a wall or other vertical support. A generally planar sheet of plastic of generally uniform density is divided by longitudinally-spaced, laterally-extending hinge elements into rectangular sections. The hinge elements are created by miter cuts in the sheet of plastic which do not extend the full thickness of the sheet thereby providing a thin hinge of plastic which functions as the hinge. The rectangular sections are foldable about the hinge elements into a hollow tube which functions as a wall attachment member. At least one of the rectangular sections functions as a shelf member which is supported at one end by the hollow tube. Other rectangular sections may be folded to form a return or nose at the front of the shelf which may be formed with an opening to display a label. Additional rectangular sections may be folded about the sides of the shelf to form strengthening members. Screws, rivets or welding with heat are used to hold the sections together.
