Airmail stamp

With aviation developments, several countries started to experiment with flights, and postal authorities considered flying the mails.

This led to an expansion that includes the collection of covers, and other postal items carried by aircraft.

[6] Specialised catalogues and albums are produced for collectors of airmail stamps and other aerophilatelic items.
