Description

This is a lot of 26 individual pieces of EXCELLENT MINT CONDITION V Mail envelopes.
Not just one piece, there are 26 pieces.  Each is in the same excellent mint condition.
We used these during World War II to write my father who was serving overseas in North Africa and Italy.
V-mail correspondence was on small letter sheets, 17.8 by 23.2 cm (7 by

According to the National Postal Museum, "V-mail ensured that thousands of tons of shipping space could be reserved for war materials. The 37 mail bags required to carry 150,000 one-page letters could be replaced by a single mail sack. The weight of that same amount of mail was reduced dramatically from 2,575 pounds to a mere 45." This saved considerable weight and bulk in a time in which both were hard to manage in a combat zone.
In addition to postal censorship, V-mail also deterred espionage communications by foiling the use of invisible ink, microdots, and microprinting, none of which would be reproduced in a photocopy.
