Abstract: A record album and slip case cut and folded from sheet paper board stock to provide a relatively flat box-like container having similar side panels spaced apart a limited distance and having one open end provided with a relatively long access notch extending inward from the edges of the side panels of said container in which the access notch is formed and bounded therealong by smooth reinforced edges resulting from tongues of the material folded inwardly upon the inner surfaces of the side panels and secured thereto by adhesive, certain of the tongues being of substantial size to afford protective stiffness to a substantial area of the side panels extending inward from the edges of the access notches, whereby no raw board edges appear on the boundaries of the open end and access notches therein.
