ABSTRACT:
The present invention relates to improved stamp hinges that may easily and quickly attached and detached from the back of a postage stamp, either used or mint, without leaving an adhesive residue on either the stamp or on the substrate on which the stamp is mounted. The hinges are pressure-sensitive and adhere by finger or slight contact pressure. The contact, surface of the hinge is partially coated with a water-insoluble, low-tack adhesive. The contact surface has a non-coated area preferably extending along at least the entire length of one edge or one end thereof. The non-coated area comprises from about 5 to about 95 percent of the area of the contact surface.
