ABSTRACT:
In accordance with one aspect of the present invention, there is provided an improved display sign system including a sign face and a plurality of vertically spaced longitudinal ribs defining tracks located on the sign face. The longitudinal tracks are designed to support indicia elements adjacent the sign face. In a preferred embodiment, the sign system further includes two side frame members disposed on opposite lateral sides of the sign face, each including a curved surface which is substantially flush with the sign face at its lateral side edge. The curved surface extends outwardly and away from the lateral side of the sign face to provide a guide for inserting indicia elements within a longitudinal track from the front side edges of the sign.
