I want to express my sincere thanks to our Validating
sergejnowo for help in tracing the paintings.
His immediate response to the request for help to find the three images sketches, disappeared from sight in 1992.
This is an Italian sketch, from which was subsequently painted, and two French etude. All three works were sold at auction in France. I want to draw your attention that the signatures on the front part were dorisovany dealers or auctioneers. For more luchshesti.

Here are the sketches and painting.
sergejnowo, once again thank you very much!
