Each unit of the stock for a match-the-hidden-indicia game includes a base sheet (12) printed on one face (14) with a visually ascertainable pattern of indicia (16), and a cover sheet (22) also printed on one face (25) with a visually ascertainable pattern of indicia (26), which may or may not match the pattern on the base sheet. The one face of the base sheet on at least a band including the pattern of indicia, is provided with a transparent coating of permanent adhesive (18), and a liner layer (20) is facially adhered thereto. The relative attraction of the permanent adhesive for the one surface of the base sheet and the liner layer is such that any attempt to remove the liner layer will substantially disrupt the one surface, thus giving evidence of an attempt to tamper with the pattern of indicia on the base sheet. The cover sheet (22) is temporarily facially bonded to the liner layer to base sheet (12) in such a way as to obscure the pattern of indicia on the base sheet from view until the temporary bonding (24) of the cover sheet to the liner layer is disrupted, e.g. by peeling or tearing it away. |
