The Post & Go stamps in this series feature six images of mail transported by air: the first UK aerial mail in 1911; a 1919 military mail flight; international airmail 1933; domestic airmail 1934; flying boat airmail 1937 and Datapost aircraft from the 1980's.
Our coin cover encapsulates a 1919 penny for the year in which the RAF commenced a mail-carrying service from the UK to troops based in Germany. The image shows a British 'Tommy' writing a letter to his loved ones at home and carries an Airport Way, Birmingham handstamp.
