Abstract: The portable exhibit system includes a plurality of display modules each of which has a pair of identical mirror image side support extrusions having a plain display panel or an illuminated display panel detachably connected therebetween. Up to three modules may be vertically interconnected at oblique angles relative to each other to define a display unit having a substantially concave continuous display surface with the bottom module having a pair of horizontal extruded support arms identical to said side support extrusions extending rearwardly therefrom. An illuminated header module may be detachably connected to the top end of the upper module. A plurality of display units each of which is comprised of a plurality of modules may be interconnected in side-by-side or back-to-back relation to provide an expanded exhibit system.
