Abstract: An apparatus for displaying materials and combinations of materials including a main rail and a plurality of side rails positioned serially one after each other. At least one side of each side rail is connected to the main rail by a switch. A plurality of panels on which the materials to be displayed are mounted are connected to the main and side rails by moving means such as guide rollers so that the panels can be moved along the rails. Each of the moving means includes a vertical shaft on which one of the panels is mounted with the panels being freely rotatable about the vertical shaft. The side rails are spaced apart from each other a distance greater than or at least substantially equal to the width of the panels.
