Abstract
Abstract An advertising display device, particularly adapted for portable, backlighted signs, includes a clear, protective pane covering a translucent sign or card on which the copy is imprinted. The pane is provided with marginal flaps and sealing strips which envelope the edges of the sheet. When the assembled sign and pane are inserted in position in a hinged door frame panel, and the frame closed against a housing, the sealing strips are brought into sealing engagement with a flange extending from the housing to hold the sheet firmly in place, thus preventing entry of moisture and foreign matter.
