ABSTRACT:
A sign comprises a frame having a rectangular front wall and side walls peripherally joined to the front wall. The side walls extend rearwardly from the front wall to define a rearwardly opening cavity. An aperture is defined in the front wall and includes an interior peripheral edge. Ledge means are joined to the front wall around the interior peripheral edge, extending rearwardly and inwardly therefrom. Display panel means, having a shape congruent with the aperture and sized for reception within the aperture, are supported by the ledge means. The frame comprises a pair of side members, each including an elongated central section and a first end section and second end section extending perpendicularly from the central section. Means are provided for linearly attaching each first end section to the second end section of the other side member.
