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.

Storage for additional transparencies and drawing materials is also provided in the housing.
