Abstract: A modular display rack comprises a plurality of removable, translucent panels that can be edge-illuminated by a captivated fiber optic lighting system. In the best mode, the system forms a single rack, although two or more racks can be combined side by side. The translucent, etched glass panels are maintained in a selected three-dimensional orientation, for colorfully displaying selected written or pictorial indicia or artwork, by rail assemblies between which they extend. The rail assemblies comprise stacked, modular parts that may be snap-fitted together by the user. In the best mode a decorative trim piece having a convex or profiled top mounts upon a lower rail. In another alternative embodiment, wherein layers of panels are deployed, a stack of rails is used instead of a single rail. Each rail is secured to a lower shoe, that is fastened to a baseplate or a supporting surface. Pins projecting from the shoes lock within rail keys, and pins projecting from the rails lock within trim piece keys.
