North Vietnam, The Councils of Nghe An and Ha Tinh, September 12th, 1965, Michel Nr. 397-398; Two stamps were issued in the nominals of 10 xu and 12 xu perforated 11.0. Due to lack of single franking postal history it is not clear what the intention was for the 10 xu value (inland postcards only cost 6 xu), so, it may simply be an extension value.
Mint blocks of four:
These stamps were not officially released imperforate but a very small number of imperforate trial proofs have come to market. Here is a specimen that is printed on both sides of a light carton that had already previously been printed on. Both sides are shown.
