National Liberation Front, Fruits, March 1976, Michel Nr. NLF 61-63; Three stamps with nominals of 20D, 30D and 60D (in South Vietnamese currency) were issued in perforation 11.0. The stamps were produced by the Tien Bo Printing House in sheets of 100 stamps each.
Small errors do occur. Below is a mint block of four of the 20D value on which the bottom right stamp shows a small printing flaw of an object that must have fallen onto the printing plate.

Here is the cancelled to order set.
These stamps are very hard to find on postally used covers. Here is a mixed franking of the 20D value along with the 6xu National Assembly stamp paying an overall postage of 26D on a letter sent from Da Nag to Qui Nhon in 1976. While there was no 26D letter rate there was a 25D rate that applied shortly after the end of the war in 1975.
Another mixed franking of the 20D value along with the 30D value of Anniversary of the Occupation of South Vietnam stamp paying an overall postage of 50D.
