These beautiful postcards were sent by Dasha! They show Belarussian artists's paintings; the first one is the "Night on Christmas Eve. (Interior with Christmas Tree)", by Stanislav Zhukovsky (1875-1944, a impressionist painter), painted in 1904. The second postcard shows the "Blue Chapel", painted in 1912, by Vitold Byalynitsky-Birulya (1872-1957, a soviet landscape painter). The both paintings are oil on canvas and they're located on the National Art Museum of the Republic of Belarus. She also sent me a candy wrapper from her favorite candy, called "Stolichnye-Elite".
