ABSTRACT:
A retail coupon document contains two paper coupons which are hidden from a coupon user, the coupons being for different values. The user selects and pulls one of two intersecting pull strips, thereby revealing one of the coupons and destroying the other, depending upon which pull strip is selected. The pull strips are formed by perforated division lines which are so arranged that each pull strip passes through one of the coupons, whereby the revealed (non-destroyed) coupon will possess perforations of one of the pull strips. The pull strips are oriented parallel to a longer dimension of each coupon and parallel to the grain of the paper.
