Abstract
An envelope which may be cut from a single piece of sheet material comprising a plurality of flaps, the front and rear of which are fitted with adhesive strips for sealing and for holding a photograph. The flaps are disposed so that an attached photograph may be covered and protected in the mail. Perforations or die cuts define a removable portion of a writing surface, removal of which makes the photograph visible from outside the envelope. The flaps are cut and disposed so that alternate procedures of refolding and resealing provide a frame for the photograph which may be placed on its side or its end.
