ABSTRACT:
A wagering, promotional or novelty product having a concealed message includes a sheet having an outer surface, ink visibly disposed on the outer surface in a first pattern, and transparent film overlying at least a portion of the inked outer surface and secured to the ink on the outer surface 8ortion in selected differentially adherent patterns, the first pattern being visible through the film. Removal of the film from the inked outer surface portion also removes the ink in one of the selected patterns to reveal a desired pattern of deinked outer surface and thereby render visible the previously concealed message.
