Tell me author
 

Dear forum users! Help please identify the author of this nice work. On the back of the work as well as on the front right in the middle of a worn inscription Chojnacki from the same handwriting. Man from whom I bought this work argues that it belonged to relatives of Mikhail Sholokhov. All the necessary photo attached.

Alas, there is no reason to think that this Chojnacki - the name "hero" figure.
Or some of the former owners. Only one thing remains - is the name of the artist.
In this direction, and should keep looking.
And who was the thing to this ... that might upset you say that it is a collection of Prince NN? :)

The initials of the artist listed on the second photo .......:(

Alas, so even easier to search the sites.
