Rare single franking of the violet 12 xu stamp on a letter to Budapest, Hungary, paying the correct triff at the time.
Letter with the complete set in pairs sent one day after the First Day of Issuance to Klewitz in West Germany. The cover also is an interesting mixed currency franking of old and new Dong and a mixed franking of service stamps (Mot Cot Pagoda issue) and regular stamps. It is not quite clear how the sender obtained the service stamp as their distribution was limited to Government Bodies, foreign embassies and NGO’s (like the Red Cross for example). The 200 Dong in pre March 1959 stamps were devalued 1,000:1 which meant that in 1965 thew were worth 20 xu. The overall franking hence amounted to 1.12 Dong which is just a whisker above the required tariff of 1.10 Dong for a standard registered letter to Western Europe.
Mixed franking of the 50xu Geneva Agreement value together with the 12xu Anniversary of the Revolution stamp and the 12xu World Union stamp for an overall postage of 74xu on an air mail letter to Paris, France.
Mixed franking of the 1 D Woschod value together with six Five Year Plan, World Union Conference and three Wild Animal stamps paying an overall postage of 1.78D on this rare registered letter sent from Gia-Loc (small post office) to Switzerland.
