ABSTRACT:
Sheet wall covering imprinted with one scene or artistic representation in ordinary ink for viewing under natural or artificial lighting conditions is overprinted with another scene or artistic representation that is visible only in total darkness after first having been exposed to visible light by the use of inks comprising visible-light-actuated, pigmented phosphors in a transparent vehicle. The two scenes or artistic representations printed are interrelated to carry out a common theme when viewed sequentially.
