Quick Summary

An aerogram, also known as an air letter, is a lightweight sheet of paper that is folded and gummed on all sides, designed for sending correspondence via airmail. This form of mail was introduced in Britain during World War II as a practical and inexpensive way to write to military personnel serving overseas. Aerograms are recognized by the Universal Postal Union (UPU) and are available in most countries. The development of airmail, beginning in the early 20th century with the advent of airplanes, revolutionized postal services by offering speed and reliability over surface transport.12
