Rhodesia and Nyasaland 6d aerogramme sent for Zomba (25 JUN 57) to the US. As the aerogramme rate to the US was 1s, the aerogramme was short paid by 6d, i.e. 50%.
Two-line instructional handstamp “Withdrawn from Air Mail / By Surface Route” to indicate transfer by surface mail.
The permit holder for license #14 was QANTAS Empire Airways Limited.
Cornish #14.2 (New subtype - No QANTAS logo below the “By Air Mail” box).
Light-blue paper with blue overlay and blue printing, IMPERIAL AIR MAIL watermark, year code „C“ for 1950. Stamp box omitted from overlay.
Sent from Calcutta (27 APR 52), India, to the US. Instructional handstamp “Sunday Posting Detained”. Franked at 10 AS.

Presentation poster for the 1979 Sir Rowland Hill Centenary aerogramme (Greiner/Greiner #85)
Greiner/Greiner #10 (“R” of “Air Letter” extends beyond the “By Air Mail” box; “T” of “Sent” is centered vertically below “ET” of “Letter”)
Sent from Knockholt (7 FEB 53) to Jamaica. The addressee has already left and moved to Trinidad. Franked with a 6d Jamaica stamp and forwarded from Myrtle Bank (FE 12 53) to the new address where it arrived two days later (receiving cancels on reverse).
Canadian Armed Forces air letter form used for civilian communication.
The air letter was originally posted unpaid on 26th December 1944. The postal authorities marked the air letter with "Returned for Postage" and returned it to the sender. The air letter was posted again, with the correct 10 cents franking for India, on 28th December. This is a bit difficult to see, as the two machine cancels overlap.
Also, the air letter received a "O. A. T" (Onwards Air Transmission") handstamp.
"It is thought that an OAT cachet was applied to the top letter of a tied
bundle of up to 60 letters. These bundles always travelled in open mail
bags to a single intermediate or final destination, but where the
quantity of mail was insufficient to warrant a closed bag. Closed mail
bags did not attract OAT markings, as the whole bag was sealed and all
letters went to the one destination as marked on the outside of the bag.
Open mail bags were resorted en route as required and bundles replaced
into other bags for the next section of their journey."
