Abstract Easel assembly comprising a folding frame having front and rear legs with a drawing board mounted on each set of legs. Each drawing board includes a generally planar backboard and a transparent overlay having an erasable drawing surface, with a space between the backboard and the overlay for holding drawings and other materials in position to be traced on the overlay. One of the drawing boards is slidably and pivotally mounted on the legs for movement between raised and lowered positions for use by persons in standing and sitting positions.
