Abstract: A display having mechanically changeable characters and a support for the display are disclosed. The display comprises an array of mechanical flip-flop elements which can each be rotated between two orientations exposing one of two visually different sides. The flip-flop elements are bars secured resiliently by springs to a frame in such a manner that each flip-flop element can be manually pulled away from the frame, rotated to change its orientation, and released to snap back against the frame. The flip-flop elements are arranged in groups of seven, each group having its seven flip-flop elements arranged into two adjacent quadrilaterals of equal size, one flip-flop element being common to both quadrilaterals. Channels are provided on the rear side of the frame to receive the springs. Various lengths for the flip-flop elements are disclosed. The support maintains the display in an elevated position and draws up the display by means of a retractable cable. A securement device holds the display up.
