As all local letters this stamp is very rare on postally used correspondence. Most local letters were destroyed in the multi-decadal war, the tropical climate and recycling due to raw material shortages. This letter was sent by a member of the military (note the Hom Thu number in the sender line) from Than Hoa to Hanoi. Hanoi machine cancel on the reverse.
Another very rare local letter sent from Lang Gia (small post office) to Hanoi in April of 1961. The stamp is slightly damaged on the right, nevertheless still a worthwhile item for any collection as this stamp is so hard to find on cover.
