An airmail stamp is a postage stamp intended to pay either an airmail fee that is charged in addition to the surface rate, or the full airmail rate, for a piece of mail to be transported by air.
Airmail stamps should not be confused with airmail etiquettes, which are affixed to mail as an instruction to the postal authority that the mail should be transmitted by air.
Famous quotes containing the word stamp:
“Only a still place
and perhaps some outer horror
some hideousness to stamp beauty,
a mark no changing it now
on our hearts.”
—Hilda Doolittle (1886–1961)
