Abstract: A modular sign comprises a perforated base having a multiplicity of apertures spaced a predetermined distance apart in both horizontal and vertical directions and a plurality of sign modules--positioned on the base. Each sign module has at least two registration projections on its rear surface for engaging two of the apertures in the base. The projections are located with respect to the edges of the sign module such that the edges of adjacent modules are separated by a predetermined distance to create a reveal between adjacent modules when the registration projections are placed within appropriate ones of the apertures. The sign modules are held in place on the base by one or more of an adhesive, a magnet, or a mechanical lock.
