ABSTRACT:
A lightweight magnetically attractive display device includes a relatively thin sheet-like intermediate layer which is adapted to be magnetically attractive at spaced intervals and which is supported in a generally planar configuration, and an outer face sheet adapted to be attached to the device in front of and adjacent the intermediate layer so that magnetized indicia characters can be removably attached to the device, against the outer layer, by the magnetic attraction between the intermediate layer and the magnetic portions on the indicia characters. As preferably embodied, the intermediate layer comprises a lightweight mesh screen made of magnetically attractive material. Alternatively, the intermediate layer may comprise a plurality of closely spaced magnetically attractive strands or a sheet of lightweight material having magnetically attractive particles dispersed therein. Advantageously, the outer face sheet is generally translucent to enable light to pass therethrough for highlighting the message formed by the indicia characters, which are preferably opaque. Also advantageously, two intermediate layers may be supported from a frame, with two translucent outer face sheets attached to the frame adjacent each of the intermediate layers, and an illumination source can be positioned within the space between the two intermediate layers for illuminating the messages attached to the two sides of the device.
