|Comments:||The British Postal Administration issued the first aerogrammes (inscribed “Air Letter”) on the 30th of March 1964.
The first Aerogramme (ADAG-1) has the value of 30 Naye Paise and carries a portrait of Sheikh Shakhbut bin Sultan al-Nahyan similar to that of the first Abu Dhabi stamps. It is printed on light blue un-watermarked paper with a carmine-red stamps imprint with blue printing. The block for the Sender’s name and address has four dotted lines of different lengths.
The Instruction Line reads, “To open cut here” and this instruction only appears on the bottom flap. The size of the aerogramme, without the inclusion of the flaps) is 20 x 24 cm.
