'Show It' Chart Paper Pads of chart paper are ordinarily glued together by means of a layer of adhesive material at the top of the sheets. Once detached from the pad, the sheets cannot be returned to the pad or placed on a vertical surface without applying additional adhesives or masking tape. Subsequent removal from the walls often results in the paper being torn, or the walls being damaged or left with adhesive on them. In this invention, a pressure sensitive adhesive is applied to the back of each sheet on the top 10 cm. Sheets can be removed from the pad and placed on any flat wall surface. The sheets can be easily removed from the wall without damaging the wall or leaving any adhesive behind. In addition, sheets can then be placed on top of one another for future use or returned to the pad.
