North Vietnam, 75. Birth Dayof Ho Chi Minh, May 19th, 1965, Michel Nr. 363-364; Two stamps with the nominals of 6 xu and 12 xu were released perforated 11.0.
Printing flaws do occur. Take a look at the stamp on the right hand side. It shows a print flaw that looks like HCM had suffered a major facial wound. This was most likely caused by dirt falling on to the printing plate
Letter with a pair of the set mailed on the Day of First Issuance by registered letter to Klewitz in West Germany. Overall postage applied amounted to 1.14 Dong which was just a whisker above the required rate of 1.10 Dong for a standard registered letter to Western Europe.
Rare multiple franking of the 6xu HCM value for an overall postage of 18xu. The letter back flap was left open on purpose for postal inspection so this mailing most likely represents a printed matter mailing.
Here is an air mail letter featuring a strip of four of the stamps plus one 6 xu stamp of HCM 75. Birthday issue for an overall postage of 52 xu. This was just a whisker above the required tariff (0.50 xu).
Very rare express mail letter sent to Klewitz in January of 1976. The letter carries the 6 xu value of the set plus some im-perforated stamps from the working elephants and traditional sports sets. Im-perforated stamps on postally used cover are very rare. The overall postage of the letter amounted to 3.48 Dong which appears to be in excess of the required tariff of 1.50 Dong. Fulda arrival cancel on the reverse.
