Display sign

Abstract

A display sign is disclosed for displaying printed matter on a backlighted poster or the like. The sign includes a display case defining a first compartment containing a light source, the display case having a front opening for the transmission of light therethrough. A closure panel is adapted to cover the front opening, the closure panel having a central transparent face panel. A concave translucent diffuser panel is located between the face panel and the light source so that the curvature of the concave diffuser panel extends toward the light source to define a second compartment between the diffuser panel and the face panel. VELCRO fastening means locate and retain the poster in the second compartment spaced between the closure panel and the concave diffuser panel. Vent openings communicate with the second compartment for the circulation of air around the poster. The concave diffuser panel and the vent openings help to prevent the accumulation of condensation in the second compartment and consequent moisture damage to the poster.
