Recycling used paper stocks is a sure sign of austerity in the wake of war; the early stamps of Latvia printed on the backs of unwanted maps, for example, are well known. Burma did not produce its own stamps until the ‘seventies, but here’s an example of a very similar piece of thrift.
We often forget just how desperate things were in the years of civil war immediately after Burma’s independence (a civil war that continues even today in the shape of sporadic separatist fighting). In 1949 the countryside was largely controlled by the ‘multicoloured’ insurgencies of the ‘White Flag’ and ‘Red Flag’ communists, the ‘White Band’ PVO, and Karen and Kachin forces, among others. At one point the beleaguered ‘six mile government’ of U Nu was pretty much blockaded into central Rangoon. Hardly surprising that the administration was forced to improvise, official stationery included.
Here is an official cover and a half (the reverse of the envelope) from Rangoon in April and June of 1951. Both are printed envelopes with “On State Service” replacing the old “OHMS” heading, so printed after independence, and both on the backs of pieces of maps. That on the full envelope (opened out here) shows a small patch of Karen State, curiously enough.
Postscript – Mike Whittaker writes: “I have two covers made from maps. One is a 1948 home-made newspaper wrapper from Rangoon University to London made from a map of an area of Siam (sic) by 12th Army Survey HQ, September 1945 and the other is an official cover from Taunggyi to New York, 1951 and made from a map of the Migyaunglaung area of Tenasserim.”
Here are Mike’s covers, inside and outside. The official envelope (below) is a match for mine.
