Abstract
Abstract A drawing toy including a housing supporting a roll of paper for rotational extraction and a battery powered light source. The paper passes over a light transmitting platen disposed above the light source and a selectively insertable transparency bearing a graphic design. An opening in the housing provides access to the portion of the paper passing over the transparency, platen and light source to permit repetitive tracing of the graphic design. Storage for additional transparencies and drawing materials is also provided in the housing.
