  • Patent number: 6042113
    Abstract: A game or gift shaped as a simulated matchbook cover containing one or more tear-out strips anchored to the lower end of the cover in essentially the same fashion as matches in a conventional pocket matchbook. The strips are elongated panels which can be torn from the cover, and which bear messages on one or both sides. Alternatively, the strips are tear-out envelopes in which messages or small gifts are inserted. In one form, a spinner is rotatably secured to the cover, and the resting position of the spinner designates one or more specific strips to be torn from the cover.
