The back of the postcard gives the name of the artist and the title of the painting. However, I had hard time gathering information about the painting on the postcard since it's in Russian. I was, however, lucky that I was able to translate the name of the artist. I got that name of Vasili Evmenevich Savinsky, but I was not able to find a biography of the artist. The painting on the postcard is a actually a portrait, but couldn't find the title of the painting itself or the name of the lady.
I just hope that somebody can recognize the painting or have information on Savinsky.
