Abstract: A display sign and system having a plurality of support strips removably attached to a back panel where the support strips have channels in opposite sides thereof, where the channels and sign members disposed in the channels overlap one another, and where the outside walls of the support strips are coterminous with the bottom walls of the channels. The sign members engage the channels of adjacent support strips at an inclined angle. Display adapters sized to engage the channels provide support for pictorial displays parallel to the back panel. Arms depend from the support strips and extending to the adjacent support strip to block light from escaping the display sign. Rows of vertically-spaced holes in the back panel and corresponding hooks on the strips provide means for uniform and rapid assembly.

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.
