The Postal Administration also issued an aerogramme on February 7th, 1973 (folded letter) with the image of the 2D stamp but a nominal value of 60D. However, the aerogramme tariff was raised to 75D on the same date which required the addition of manual surcharge hand stamp in the amount of 15D (SICP Journal Volume from February, 1974, 4 Nr. 1). Some of these unissued aerogrammes have come to market. Here is the mint aerogramme without surcharge.
Inflation was rampant in South Vietnam so postal rates had to be changed often, especially in the late years of the Republic until 1975. As explained above the 60D aerogramme was already rate redundant when it was issued and as a result was sold with a 15D surcharge. Here is the 15D on 60D surcharge in red paying an overall postage of 75D in May of 1973 and sent to the Japan. Surcharges in other colors (violet, blue, black, green) have been reported
Here is the same aerogramme but this time used by the indochinese Garuda IV Contingent that was sent to Vietnam in 1973 and 1974, towards the end of the war, as peacekeepers. Sent to Canada in April of 1973 paying an overall postage of 75D.
An additional surcharge was required on this aerogramme front sent from Da Lat to France in November of 1973. Apart from the 15D red surcharge stamps from the Reconstruction after TET Offensive and Fishery sets with a nominal value of 15D were added for an overall postage of 90D.
Here is a rare mint aerogramme that carries two surcharges. First the one for the additional 15D that was used in the first half of 1973 and the additional 25D surcharge applied due to the tariff increase from 75D to 100D. The effective date of this tariff increase was February 1st, 1974 (SICP Journal Volume VI Nr. 2, May/June 1976).
Postage kept creeping up and so a different surcharge of 50D on top of the 60D nominal value of the aerogramme for an overall postage of 110D can be found as of July 22nd, 1974. The aerogramme was used in October of 1974. Below are two postaly used samples sent to the United States.
