Registered air mail letter sent in December of 1986 as a mixed currency franking from Ho Chi Minh City to Klewitz.

The Communist Party stamps are in the rare perforation of 12.5. Souvenir-Sheets on postally used cover are very rare. The Hanoi Liberation, Friendship stamps and the World Communication Year souvenir-sheet were still denominated in old Dong. The Vietnamese Government conducted a devaluation of the Dong on September 14th, 1985. This meant that all stamps issued prior to this date were only worth one tenth at the time of mailing.
