Abstract
A member, such as a sheet of paper or plastic, is coated with phosphorescence glow on the dark material and then layered or coated with photographic emulsion so that an image can be produced on the surface of the member by a photographic process, and thereafter, an image can be produced on the surface by illumination means. In another form of the invention, a sheet of paper or plastic has luminescent material incorporated therein to cause one side of the sheet of material to glow in the dark. The sheet is assembled onto a clipboard and thereby provides means by which a written message can easily be formed in the dark.
