An Aerophilatelic exhibit is composed essentially of postal documents transmitted by air, bearing evidence of having been flown.
An Aerophilatelic exhibit should represent a study of the development, operation or other defined scope of airmail services.
The transportation of mail by air may be shown in several ways : by adhesive stamps, vignettes (with and without face value), labels, cancellations, cachets, transit, route and other explanatory markings, written endorsements, backstamps and relevant signatures.
