Maps, charts, and diagrams.-A device for drawing attention to any point on a diagram or article exhibited comprises panels A mounted on a demonstration board E or the like, and having recesses or other means for holding strips B of cardboard &c. on which are data relating to a certain point on the diagram or article, a pin or other marker C being located adjacent to each strip B, and attached to a cord D passing through a hole in the panel or board. The markers, which are held under tension by springs or elastic, can thus be placed at any point on the board, and return to normal position when released. The panels may be used separately from the board.
