ABSTRACT:
An advertising display includes a spherical styrofoam ball having a luminescent outer coating and means for hanging the sphere on a variety of supports. The supports may include automobile antennas and lines hung across billboards. The advertising system would include hanging a plurality of these spheres at spaced intervals on a line with wind generated motion providing means for attracting attention to the sign. Shapes other than spheres may be used. Another aspect of the invention is a method of manufacturing a display device which includes pushing a wire through a styrofoam sphere, bending an inserted end of the wire into a hook, and pulling the hooked inserted end back towards the sphere, thereby embedding the hook in the sphere. An opposite end of the wire is provided with a fishing line spinner for connecting the sphere to a support while providing a universal joint so that the sphere can freely rotate.
