发明名称 Poster board display system
摘要 A poster board wall display system comprising a foamed polystyrene board, smaller than the poster board to be hung to the wall, with an opening having a tapered or slanted upper edge to engage a fastener (e.g., nail or hook) protruding from the wall. The outer face of the foamed polystyrene board is equipped with a fastener means (e.g., VELCRO strip) that reversibly engages to the backside of the poster board. In this manner, a poster board can be suspended away from the wall during display and the particular poster boards being displayed can be readily repositioned or changed.
