Nadya Krupskaya was young?

It has value, and then only for you, if the lady depicted in the portrait is brought to you some relative.

Yes, there are similarities.

It is possible that the author was partEyny.

Look at it is as if her money and should not give.
:D> Hope springs eternal!

Probably 1950s, someone who had been studying, say, at the Surikov Institute.

Special value is not, all sketched in good faith, but boring, boring, and facial expression can only alienate any collector.

Inextricably skazanuli :D>

Yes it seems very, well, if not revolutionary, Krupskaya then in my opinion, still the same.

Let me forgive the topic , but I think it was the last portrait of the artist , who had not had time to become famous :)>

I agree with you , especially on the face. My opinion is that it will be extremely difficult to find what you contemplate this look at home. While it may have gourmets.
