Abstract
A menu board assembly comprising a frame for displaying artwork, having a series of frame elements joined together to define the side walls of a generally parallelepiped recess. The frame is superimposed on a light box having a transparent face plate forming the rear wall of a cavity and a transparent window plate is positioned to cover the recess and is superimposed on the front of the face plate. A flexible tape connects the window plate with said face plate for pivotal movement and defines a bight at the hinge. The window plate may be pivoted from a bight-opening position to a bight-closing position to accommodate the insertion or removal of artwork.
