Mail Delivery
Through rain, snow, heat, or gloom of night, we expect postmen to deliver the mail. The U.S. Post Office handles over 603-million pieces of mail daily. Yet it represents only 43% of the world’s total mail volume. From ancient Sumerians to Pony Express, from airmail to E-mail, we follow the long journey of mail.
