<p>This invention discloses a novel device which may be used as a decal, label or the like. The device is manufactured from hard vinyl chloride film which does not have a plasticizer therein. The device may be made in any predetermined shape and is suitable for use as a label for books or may be used as a teaching aid for such subjects as language, arithmetic, music, science, social studies and the like. The device utilizes the electrostatic charge inherent in the vinyl chloride film and thus, may be detachably adhered to any surface such as paper and may be easily removed therefrom. When a combination of devices are used such as when depicting a musical score, the devices may be easily rearranged and new designs or scores created. The elimination of adhesives and plasticizers found in these devices of the prior art provides a distinct improvement by allowing the devices to be easily set up, rearranged or dismantled from the substrate.</p> |
