Rare registered express mail letter sent to Klewitz in July of 1978. It carries a block of four of the Children stamps plus one of the 12 xu Liberation of Hanoi stamps. The letter was sent from Bac Ninh but interestingly enough the R-Label was only attached in Bac-Giang. The letter was opened un-professionally during transit (as pointed out by Klewitz) which may have been a censorship move but no censor marking were indicated. The overall postage amounted to 5.08 Dong. Fulda arrival cancel on the reverse. Green Fulda custom cachet on front.
First Flight letter of Lufthansa 773 from Ho Chi Minh City to Frankfurt, Germany (October 30th, 1990). The letter carries the 6 xu Liberation of Hanoi stamp plus two of the early 1965/1967 National Liberation Front stamps. Since the currency of the NLF stamps (denominated in South Vietnamese Dong) and that of North Vietnamese stamps (denominated in North Vietnamese Dong) were incompatible these stamps were not allowed in North Vietnam. However, it appears that no one noticed this on this letter as it lipped through without any comments.
Colorful mixed currency franking of the 1,000D Handicraft stamp (that was devalued 1,000:1 on March 1st, 1959 and hence only worth 1D at the time of mailing) with other NVN stamps (including the 6xu Liberation of Hanoi stamp) for an overall postage of 2.36D on a rare registered letter to Czechoslovakia mailed in December of 1964.
Mixed franking with the entire set plus other NVN stamps (including the 12 xu Liberation of Hanoi) for an overall postage of 97xu, which was well above the required 12xu tariff in 1964, so most likely this represents a philatelic mailing.
