The airmail envelope is an iconic and historic product that revolutionized the postal industry. It originated in the early 20th century when the use of airplanes became more prevalent in delivering mail across long distances. These envelopes were specially designed for airmail delivery, with lightweight and durable paper to reduce the weight and increase the speed of delivery.
Airmail envelopes were first introduced in 1918 by the United States Post Office Department, and quickly became popular for sending mail across the country and eventually, the world. These envelopes were marked with a special airmail stamp, indicating that they were meant for air transportation.
As air transportation technology improved, so did the design and functionality of airmail envelopes. They were made with various security features, such as internal security patterns, and included windows for displaying the recipient's address.
Today, airmail envelopes continue to be used for international mailing, with some designs even incorporating the traditional red and blue border of the original airmail envelopes. These envelopes serve as a reminder of the significant role that air transportation has played in the history of postal delivery.
