In the former Soviet Union, an enormous number of postal stationery – envelopes with imprinted stamps – with a motif from the Baltic states have been issued. The official issues of the Russian Ministry of Transport in Moscow were printed in the state printing office “Gosnak” in Perm (in the Urals).
An overview of the envelopes with Latvian motif can be found in:

The first envelope as postal stationery with Latvian motif was published in 1954:
The description of the picture – the Opera and Ballet Theatre in Riga- is only in Russian. Later envelopes have also a description in Latvian.
