A game ticket which is particularly useful as a lottery ticket is claimed. The ticket basically comprises at least a base sheet and a cover sheet which are adhesively joined together in a peripheral portion. Information to be concealed is placed on the surface of the base sheet which faces the cover sheet. This information is concealed by covering it with a suitable, removable material which is opaque thus concealing the information until the opaque material is removed. In order to provide security for the ticket so that the purchaser may be sure that no one has been able to determine whether or not it is a winning ticket prior to being opened by the purchaser, a tear line of perforations extends through the cover and base sheets and the ticket must be torn along this line to gain access to the covered or concealed information. The use of postage stamp perforations helps to insure that any attempt to pry the various portions of the ticket apart will cause a tear or misalignment of holes at the perforation line and alert or warn the purchaser to the fact that the ticket may have been compromised. In addition, the cover and base sheets may be made from a laminate of paper and metallic foil further insuring the security of the ticket. In a further embodiment the combination includes a bottom sheet which is affixed to the base sheet so that a three layer ticket consisting of cover, base and bottom sheets is provided. The bottom sheet acts as a further security for the ticket and is particularly useful when impact type printers are used to imprint the concealed information.
