ABSTRACT:
A coupon document includes top and bottom paper panels releasably secured together around their peripheral edges. An exposed outer side of the top panel has first and second intersecting perforation lines. A hidden inner side of the bottom panel has first and second overlapping coupons imprinted thereon in a general L-shape such that the document can be folded and torn along either of the perforation lines to reveal one of the coupons and destroy the other coupon. The bottom panel is free of intersecting perforation lines which could weaken the revealed coupon.
