ABSTRACT:
A device for supporting drawing media which includes an easel for permitting simultaneous use by more than one person and having at least three side panels. Each side panel has a substantially planar front face and rear face, a bottom edge, and two side edges, the edges forming at least a portion of the periphery of the panel. The panels has disposed proximate to one side edge thereof, means for removably interlocking with mating interlocking means disposed proximate a second side edge of another panel. When interlocked, the panels form a hollow polygon with an open bottom, each facet of the polygon constituting a surface for supporting media to be drawn upon. Alternatively, the panels can be directly drawn upon and erased.
