ABSTRACT:
A system for displaying a number of pictures, notices, or similar announcements comprises a number of flexible sheets each provided with pictures, notices, etc. and cooperating with respective suspension devices for suspending the sheets in a divided stacker. The suspension devices, for example in the form of pins, project beyond the sheet on either side thereof and the stacker collects the projecting suspension devices so as to store the sheets, preferably hanging vertically. Each sheet is provided with a substantially stiff outer grip member which is gripped and moved by a feed system. The feed system moves the sheet and the suspension member for the respective sheets so as to displace the suspension member to sequentially display successive sheets or the like.
