Abstract
Abstract The disclosure herein describes a display sign which consists of a series of superposed slats identical in shape and supported and confined in frame members, also identical in shape; each slat includes, at its upper portion, a lengthwise groove defined by two upwardly extending resilient leg portions and, at its lower portion, a lengthwise channel having a restricted entrance portion slightly smaller than the overall distance extending between the extremities of the leg portions. Each slat further includes, on each of its front and rear faces, a longitudinally extending rail which cooperates with the rail of another slat to support indicia, such as letters, symbols and numerals. The disclosure also teaches two ways of mounting hooks on the back of these indicia in order to support them on the rails.
