V-mail. In the V-mail room at the Pentagon building, Washington, D.C., an armed courier delivers letters for filming and reproducing at the official photo mail station. V-mail is available to and from the armed forces stationed outside the United States. It is only 1/65th the weight of ordinary mail and saves ninety-eight percent of the cargo space required for ordinary letters. 1,600 letters can be placed on a roll of film little larger than a pack of cigarettes. Sourced from the Library of Congress.
