ABSTRACT:
A lottery ticket which consists of a continuous strip of sheet material is perforated along predetermined lines and folded to provide a three-layer ticket in which the lottery number is placed on the bottom layer. The perforations are disposed in the two upper layers and define areas that can be readily broken to form lug portions. The ticket number on the bottom layer can be revealed only by pulling on the lug portions which will tear off along the perforated lines. In this manner the ticket is permanently and irreparably altered.
