Abstract: A sign system particularly useful for point of purchase displays is provided. The sign system includes an elongated trough for carrying one or more folding sign members. The trough is provided with a slot which because of its dimensions allows a media portion of the sign member to pass through the slot and hang below the trough member while the top of the sign member is retained in the trough. In one embodiment the elongated troughs are carried by vertical supports which attach to an existing shelving system. Other embodiments are disclosed for supporting the elongated trough. The folding sign members have a display position for displaying any messages or graphics carried by the sign member, and a shelving accessibility position in which the sign member may be folded allowing access to any shelving hidden by the sign members while the sign member is retained in the folded position by the trough.
