- a layer of non-drying, pressure-sensitive adhesive applied only in the recessed marginal edge portion,
- a protective strip removably applied to the layer of adhesive in said recess,
- the combined thickness of the adhesive and protective strip being no greater than the depth of the recess so that the thickness of the attachment marginal edge portion of the paper sheet is no thicker than the remaining portion of the sheet to permit processing of the sheet through a conventional processing operation such as printing and copying in a conventional manner.
