Abstract: A sign system includes an upper rail and a lower rail, or upper and lower rail with one or more intermediate rails each extending between laterally-spaced vertical supports. Each of the upper rail and lower rail have a longitudinal groove running substantially along the longitudinal lengths thereof. The longitudinal grooves of the upper and lower rails are confrontingly opposed and each has a central portion with a length and lateral sides and side portions extending along the lateral sides of the central portion such that inner sides of the side portions face the lateral sides of the central portion and external sides of the side portions face away from the lateral sides of the central portion. A face plate is releaseably connected to one of the upper and lower rails. The face plate defines an outer side of one of said side portions of said longitudinal groove of said one of said upper and lower rails when said removable face is connected to said one of said upper and lower rail.
