Another one from 1992. The original envelope is a Soviet era 5kap one. Interestingly without an overprint like the stamps used during the same period. It has been uprated by the addition of 45kap which I assume is the European rate. And then an additional 450kap because it was being sent to the USA. How would you describe this? And just out of curiosity is the added postage done with some sort of hand stamp or run thru a meter of some kind?
In 1992,from March 1 to August 9,the rates for letters under 20g were : 100k for inland mail 300k for surface mail to any foreign country (even Estonia and Lithuania) 500k for airmail to any foreign country
And that franking is correct. From August 10 (1992) to February 14 (1993) the rates for a letter under 20g were,in latvian roubles : For inland mail 3 And to any foreign country 10 for surface mail and 15 for airmail
