A device for displaying price and like information wherein the figures to be displayed are contained on a series of panels folded into two stacks so that the top panel in each stack combines to make a display area and display one complete figure. The outside edge of each stack of folded panels are retained in a frame to dispose the top panel of each stack in the said display area. The outside edges of each stack are retained in the frame as aforesaid in opposed channels and a user can, by depressing the panel on the top of a stack actuate the edge of the depressed panel out of its channel, turn it over and insert it into the other channel whereby to change the panels on the top of each stack and, at the same time, change information conveyed by the top panels.
