Abstract
Abstract An envelope includes a body portion with a window opening covered by a transparent window patch. A pair of opposed side flaps are integrally connected to the body portion and are demarcated from the body portion by score lines along the edges of the body portion. A top and bottom flap are integrally connected to the upper and lower edges of the body portion respectively and are demarcated therefrom by score lines along the body portion upper and lower edges. The bottom flap is secured in overlying relation to the folded side flaps to provide a first pocket for receiving an insert. After the first mailing of the envelope, the upper portions of each of the side flaps together with the top flap and an upper portion of the body portion are severed from connection with the remainder of the body portion and side flaps to form a second pocket for receiving an insert. By securing the remaining top portion of the body portion in overlying relation to the bottom flap and the remaining portions of the side flaps, the envelope is adapted for second mailing.
