Is this envelope from Germany sent to China via the Siberian post route?
May I ask you to answer, where is the three-line text stamp on this envelope, and what does it mean? Is the residual note in Russian on the back of the envelope a Russian check?
May I ask you a question? There are Russian letters left on the back of this envelope“ При…” Is it used by Soviet Russia post? Who knows the complete content of this note?
