ABSTRACT:
A portable, lightweight easel for assisting in the tracing of figures is provided. The base has an interior volume with a projector and ancillary art supplies disposed therein. The projector has a light source and a receptacle for receiving a light-transmissible medium having at least one image formed thereon. A writing plane is attached to the main base and angled above the interior volume. It was an upper surface and a lower surface. The writing plane includes a translucent window-like portion between its upper and lower surfaces. The projector shines light through the medium and projects the image through the window and onto the lower surface of the writing plane so that the image is visible on the upper surface of the writing plane. Multiple images may be provided on a single medium, and the easel may be provided with multiple media each bearing different images.
