ABSTRACT:
A board base provides a storage and display unit for a plurality of markable white erasable presentation panels. Such presentation panels can be used with erasable marker pens. The board base can display one presentation panel and store four additional presentation panels. The board base can be adapted to permit either first side removal, second side removal, or top side removal. Set screws are provided for releasably securing these members. Indicia, such as color coded or numbered tabs permit ready identification by the user, and provide an accessible manual gripping portion for removal of each presentation panel. In operation, a selected presentation panel is removed from the framework in the board base, and the presentation panel is inserted into a front presentation slot in the lower track member. The presentation panel is positioned flush with the front board for ease of marking and viewing.
