Abstract
Abstract This invention relates to a transparent plastic envelope which has presealed therein display material visible through the envelope. The envelope is designed so as to provide both means for hanging the envelope up on a hook or the like as well as means for positioning the envelope in a ring notebook binder. Both the flap for the hook engaging means and the flap for positioning on the rings of a binder are initially sealed into the plane of the envelope and the envelope is provided with means for breaking the seal to permit the flaps to hinge outwardly for proper positioning either for hanging or inserting into the notebook binder.
