Abstract: A coupon document enables a user to reveal one of two coupons in a manner which causes the other coupon to be destroyed. The document comprises first and second panels held together along their outer peripheral edges by releasable glue. Each panel has a hidden inner side on which coupon indicia is imprinted. Each panel includes a pull strip which, when pulled off, destroys the coupon indicia on the respective panel while enabling the coupon indicia on the other panel to be revealed.

Abstract: A retail coupon document contains two 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 a downstream portion of each pull strip passes through one of the coupons. Thus, the revealed (non-destroyed) coupon will possess such downstream perforations. The perforated division lines are formed in a two-ply panel of the coupon and are arranged such that each pull strip is less resistant to being pulled off in an upstream portion thereof than in a downstream portion thereof. The division lines are formed in both plies, with the perforations in one ply being staggered relative to the perforations in the other ply in at least a downstream section of the coupon.

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 a downstream portion of each pull strip passes through one of the coupons. Thus, the revealed (non-destroyed) coupon will possess such downstream perforations. The perforated lines are configured such that each pull strip is less resistant to being pulled off in an upstream portion thereof than in a downstream portion thereof. This ensures that the revealed coupon will not be unduly weakened by the presence of perforations therein.

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.

Abstract: An adjustable rack for books is provided which includes a pair of supports aligned in parallel spaced relationship and a pair of end plaques removably mounted on the supports. Each end plaque lies in a plane normal to the plane of the supports. One end plaque is mounted in a fixed position on a corresponding pair of ends of the supports, while the other end plaque is movably mounted on the supports relative thereto. The longitudinal body of each support includes symmetrically aligned radially extending ribs, and each support terminates in discrete pairs of legs having outwardly turned feet, which releasably engage a plaque on the support. A pair of corresponding ends of the respective supports are gusseted for the purpose of releasably fixing the position of one of the end plaques on the supports.
