Abstract: An interchangeable sign system for locating indicia relative to a predetermined display includes an integral support member having a spacing portion and a retaining portion, and an indicia bearing member having a front indicia bearing surface and a flat rear surface including a retainer for freely, slidably engaging the indicia bearing member and the support member. The retaining portion and the spacing portion are not collinear but intersect at a junction to form an intersecting angle of between about 10 degrees to 170 degrees with respect to the spacing portion to orient the indicia bearing member in the line of sight of an observer when the indicia bearing member is above or below the observer's level line of sight. In the preferred embodiment, the retainer defines an open ended channel superbonded to the rear surface of the indicia bearing member.
