Airmail Stamps - It is rarely appreciated that it was the movement of mails rather than of people which was seen as the main benefit of early air travel. When has man not seen faster communication as a great prize? We take it for granted now but for decades Air Post services were merely an option, and an expensive option at that than the cheaper alternatives of long-established shipping and overland routes. These special rates needed special stamps to raise the correct revenue and importantly to also allow the postal authorities to clearly identify mail bound for the airport. The earliest airmail stamps such as the Colombian 1919 issue with its basic local overprint speak of the dangerous, unregulated and arduous nature of early air transport and perhaps the USA 1918 24c “Inverted Jenny” captured the imagination of philatelists more than any other air post stamp since.
