Abstract: A graphic communication medium is disclosed in which a dry pastel substance is placed in solution and uniformly applied over a substrate such as paper. The substrate may include a drawing beneath the pastel such that areas of the drawing may be highlighted by selectively removing the dried pastel from the area to be highlighted. The highlighted area is then re-covered by rubbing pastel from adjacent areas of the substrate thereover.

Abstract: This invention pertains to the fields of graphic arts and graphic communication. The principal use of this invention is to communicate visually with a new graphic method--a method of putting a translucent overlay on one color of pastels uniformly on a piece of paper and then removing it by erasure in order to create a desired image. The paper can be imprinted before the overlay is applied in order to give a foundation for the erasure. One prior method of graphic communication has been to put a color or several colors on a paper nonuniformly to create a desired image. Likewise, another prior method has been computer-generated images on cathode ray tubes. Both of these prior methods require training and skill. Neither are easily accomplished. This new method requires no artistic or computer skill and gives excellent results. Further, this new graphic method can be renewed by rubbing the translucent overlay back to a uniform color and an additional image created by erasing again.
