North Vietnam, 20 Years Republic, September 2nd, 1965, Michel Nr. 394-396; Three stamps all in the 12 xu nominal and perforation 11.0 were issued.
Mint set in blocks of four:
Small printing errors did occur. Here is a mint and used double print of the black color which was caused by the vibration of the rubber mat used in the offset printing method as a result of improper tension settings.
Here is a perforation error that occurred due to a paper fold in the sheet. When it was later unfolded the top left stamp was left partially imperforate on top.

Registered letter mailed to Klewitz on the First Day of Issuance of the 20 Years Republic issue and featuring a mixed currency franking and the complete set in pairs. The Jade Temple stamp from 1958 of 150 Dong had been devalued by 1965 (1,000:1) so it was only worth 15 xu and the overall franking amounted to 112 xu which was 2 xu above the required postage for a standard registered letter to West Germany.
First Flight letter of Lufthansa 773 from Ho Chi Minh City to Frankfurt, Germany (October 30th, 1990). The letter carries of the 12 xu 20 Years Republic stamps 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.
