A display system comprises a display substrate 2, including an adhesive layer 5 or other means for attachment to a wall 1, and a micro suction layer 7. A graphic display sheet 3 has a micro vacuum receptor layer 9 on one side that may be provided by a varnish, and a printed display side 11 opposite to the micro vacuum receptor layer. The receptor layer sticks to, and is removable from, the micro suction layer of the display substrate. Thus, the graphic display sheet 3 can be changed without requiring additional micro suction material. Preferably the varnish providing the micro vacuum receptor layer is a silicone free polyurethane based lacquer. There may be release papers 4, 8 attached to the adhesive layer 5 and micro suction layer 7. |
