ABSTRACT:
A display device is provided consisting of a first display panel having a first forwardly facing substantially flat surface carrying a first message to be displayed with a cut in the first display panel to divide the first display plane into a plurality of sections which cooperatively produce the first message, a second display panel having a second forwardly facing substantially flat surface for carrying a second message to be displayed and also having a cut to divide the second display panel into a plurality of separate sections which cooperatively produce the second message, structure for guiding relative movement between the first and second display panels in a predetermined path between first and second relative position for the first and second display panels, structure on the first and second display panels for intermeshing the sections on the first and second display panels with the first and second display panel surfaces facing in the same direction and for causing the first message to be exposed for viewing at the front of the display device with the first and second display panels in the first relative position and for causing the second message to be exposed for viewing at the front of the display device with the first and second display panels in the second relative position, a tab on one of the plurality of sections on one of the first and second display panels that projects through the cut in the other of the first and second display panels at all times throughout the range of movement of the first and second display panels between the first and second positions. It is another aspect of the invention to configure the panel cuts so that the panels can be moved without binding between said first and second relative positions without the need for cut-outs/reliefs contiguous with the cuts.
