The letter carries perforated stamps from the Year of Peace, Birds, Labor Day, National Assembly, Communist Party sets and the souvenir-sheet from the Post Congress Hamburg set. Souvenir-Sheets on postally used cover are very rare. Apart from the Post Congress Hamburg souvenir-sheet all other stamps were already denominated in new 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. The overall postage hence amounted to 10.00 oD =1 nD. plus the stamps in new Dong (44 nD) plus the red free frank for 319 nD for 364 nD. Fragment of the green Fulda custom cachet on front.
