South Vietnam, For War Invalids, December 21st, 1952, Michel Nr. SVN 90; A single stamp was issued with a 3.30P nominal plus a surcharge of 1.70P and in perforation 13:12.5. Due to the hefty surcharge the stamp was not very popular with the general public. It was mostly used on philatelic mailings such as First Day Covers and so it is very rare on postally used commercial covers. The stamp was also issued in booklet form with four stamps to each booklet.
