ABSTRACT:
A sign or menu board has a pair of parallel vertical side rails with opposite end portions of upper and lower cross rails joined to the upper and lower end portions of the side rails to form a carrier frame. Each side rail has a track coextensive with its length. Grid modules make up modular grid units. Each unit, which may contain only one module, is comprised of cross bars that are joined at their opposite ends by tie-bars which together with the cross bars define a window opening. The cross bars are provided with lengthwise grooves for slidably accepting an information strip between them. The grid units slide into the carrier frame along the tracks and are constructed such that the information strips can be slid into or out of a grid without withdrawing the grid from the carrier frame. Pictorial assembly retainer bars are also constructed for sliding into the frame on the side rails. The laterally extending retainer bars are slotted to receive the upper and lower edges of a pictorial composite composed of a transparency between two light transmissive plastic panels. Pictorials are exchangeable without necessitating removal of a pictorial assembly from the carrier frame.
