In his notes Jack Dyckhouse, Vice President of the Society of Indochinese Philatelists, writes that most of these stamps were sold cancelled to order to Eastern Bloc nations in order to pay for the war effort. The stamps that were still in the vaults of Hanoi were taken out in 1980-81during a shortage of military stamps because of the very large number of troops involved in Cambodia. The CTO stamps were distributed and allowed to be used. Note the cover below: there is a visible cancel on the upper left corner of the stamp.
