World War II broke out in 1939 as a precursor to the development of a well-known mail processing and delivery service commissioned by the US military, Victory Mail.
At the start of World War II, the US military anticipated the difficulty of shipping large volumes of correspondence to distributors or post offices. Not only that, most cargo and aircraft carriers ware required to prioritize the transportation of troops and military equipment to the battlefield.
Therefore, a postal service based on the British Airgraph Service (a mail service by British aircraft) was born called Victory Mail, also known as V-mail. The service was designed by Eastman Kodak and was first launched on June 15, 1942, which became the primary communication between frontline soldiers and their relatives in the hometown.
A V-mail was written on a piece of paper sized by the service provider, then captured and converted into film rolls. When the V-mail was transported to the place of destination, the message would be re-launched back to its original size and printed as an image. Therefore, the writer could not use the trick to steal confidential documents, or make dark transactions.
V-mail made mail delivery more convenient and less expensive. The 1,600 mails were converted into film roll of the size of a bag of cigarettes, so 37 bags of mail were left with only one bag.
Original mails were being registered, sorted to prepare for the shoot.
V-mail was zoomed on a time machine to correct errors.
V-mail was being printed on paper by a dedicated printer.
Rolls of paper were used to print images on the letter being produced, washed through, and dried in line.
After that, the scrolling would be cut into smaller sections to make it easier for the reader to track with a special paper cutter.
The final stage was the classification of processed V-mails, prepared for the recipient.
