Since these stamps were never used there is no genuine postal history. Sometimes one can see letters that were favor cancelled after the end of the war or NLF stamps mixed in with North Vietnamese stamps also used after the war but they are basically philatelic documents that were simply made up to please collectors. NLF stamps were not permitted to be used in the North (mostly because the currency units were simply not compatible) so the mixed frankings one sees once in a while simply slipped through unrecognized or were obtained by bring the postal clerk.
The National Liberation Front was an unground army of people that often posed as ordinary citizens and farmers during daytime but became soldiers at night. This made it so hard for the Army of the Republic of Vietnam (ARVN) and the Americans to defeat them. In order to scare this underground army and erode support among the population, ARVN distributed propaganda leaflets intended as psychological warfare like this original one below (ex Munshower).
