ABSTRACT:
A portfolio presentation folder is made of a single blank sheet of cardboard for custom decoration and instant assembly by the user in a home, school or office environment. The blank sheet is separable into a pocket part and a front cover part so that the latter may be separately and independently decorated by standard office machines, desk-top publishing equipment, etc., or by hand. Both parts are provided with cutouts forming handle flaps and handle openings arranged for registry with one another so as to provide strong, multi-layered handle regions when the cover and pocket parts are connected to one another after the pocket part has been folded to form a pocket.
