A wagering, promotional or novelty product (10) having concealed messages (32, 34), comprises a sheet (12) having an outer surface (14), ink (20) visibly disposed (at 24, 26 , 28) on the outer surface in first patterns (22), and transparent film (40) overlying at least a portion of the inked outer surface and secured to the ink on the outer surface portion in selected differentially adherent patterns (22). Removal of the film (40) from the inked outer surface (14) also removes the ink in the differentially adherent patterns (22) to reveal desired patterns of deinked outer surface and thereby render visible the previously concealed messages (32, 34). <IMAGE> |
