The picture was bought in Prague. The seller argued that the author is Russian. Oil on canvas, h see Looks 50 years plus or minus. More natural colours - the first darker picture without a flash. Now there is no possibility to take a picture of the back view, but the canvas of the old "dusty". Thank you for this great community for opinions!

Author signing was obviously under a lasting impression signature Chaim Soutine...The same beloved cadmium red...Painting presents, to the last has nothing...

Thank you for your message. Heart E-Kolo, of course, but has already passed. Soutine is crossed off the list of kandidatov. Who will be next?
'll add a little. Not an expert on painting, but a big fan of (emotional consumer). Visited many museums around the world. From this picture (my subjective opinion) felt outbound encouraging energy as would be in this story - it seems to me. It is possible that it was the surge of the remaining unknown talent. In any case, I would be grateful for any messages.
