  • Patent number: 4174857
    Abstract: 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.
