This official from Russia was a double mistery. Sometimes i don't know where the image of the card is from because there's no information in english, but this time i don't know what's written on the card either, because the sender wrote in russian :o I found out this is a card from Tyumen thanks to the zip code because the sender wrote her address.
"Tyumen is a city in Urals Federal District in Russia, located on the Tura River 2,144 kilometers (1,332 mi) east of Moscow.
Tyumen was the first Russian outpost in Siberia; it was founded in 16th century to support Russian expansion to Siberia. Since its foundation, Tyumen has always been an important settlement. Located at the crossing of water and land routes, the town rapidly developed from a small military settlement to a large commercial and industrial city.
