Mail sent home by soldiers of some of Britain’s far-flung forces is speeded up by “airgraph,” a new development in postal service. Letters are written on special forms 8 by 11 inches, which are photographed on miniature film and flown to England. At the foot of the form, space is provided for writing the name and address of the recipient. Upon reaching the homeland, an enlarged print is made from the film, and this is sealed in a “window” envelope for delivery in the mail.
