Abstract
An improved display sign (10) comprising an extruded frame (12). A rear panel (14) is provided. An element (16) is for mounting the perimeter of the rear panel (14) in a removable manner to a back portion of the extruded frame (12). An inner transparent panel (18) is placed within a front portion of the extruded frame (12), so that the perimeter (18) will butt against an inner portion of the extruded frame (12). A front transparent panel (20) is also provided. An element (22) is for mounting the perimeter of the front transparent panel (20) in a removable manner to the inner transparent panel (18), so that a sign (24) can fit between the inner transparent panel (18) and the front transparent panel (20). A facility (26) within the extruded frame (12) between the rear panel (14) and the inner transparent panel (18) is for producing light, so as to illuminate the sign (24) therein.
