AIRGRAPHS AND V-MAIL
Airgraphs and V-mail (Victory-mail) include hundreds of thematic depictions and represent useful material for thematic collections. They were used for the transmission of large volume of correspondence of Great Britain and USA overseas troops. The transmission had been accomplished through microfilms. Airgraphs were for British and V-mail for Americans.
