Here is the set in mint blocks of four:
Rare single franking of the 12xu stamp on a letter sent from Hanoi to Moscow, Soviet Union in August of 1965. Moscow airport cachet on front. Moscow arrival cancel on the reverse.
Mixed currency franking of a pair of the 150D Resistance in South Vietnam stamps with one of the 3xu South Mountain Provinces stamps documenting a mixed currency transaction. The 150D stamps were devalued by 1,000:1 on March 1st, 1959 so were only worth 30 xu for the pair in 1970. The overall postage amounted hence to 73 xu. Mailings to Switzerland were still pretty rare in the early 1970’s.
Mixed franking using three of the 2xu Mountain Provinces stamp together with the 30xu Traffic Minister stamp and two im-perforated 50xu Flower stamps for an overall postage of 1.36D. Im-perforated stamps on postally used cover are very rare.

Here is an interesting mixed currency franking mailed to Klewitz in 1965. The Bay of Ha Long stamps from 1959 were devalued 1,000:1 which meant the nominal of 500 Old Dong was now worth 0.50 New Dong or 50 xu. The overall franking hence came to 1.12 Dong. This was just a whisker above the required tariff for a registered letter to West Germany of 1.10 Dong.
