United States. Marine Corps. Division, 2nd.

The process of creating V-mail, short for "Victory mail," originated in England and was used widely by the United States Armed Services during World War II. The process required special stationery, which was photographed at a reduced size. The negatives then traveled overseas, where they were enlarged, printed, and physically mailed to recipients. Nearly 10 million V-mail messages were exchanged during the war.
