It would be interesting to know the origin - Lot number 86 Strelnikov VV Authorship is somneniya.Sovershenno different technique and color saturation. Other works VV Strelnikova can be seen here
http://www.alexbrey.com.ua/showgallery/vvstrelnikov/. And yet - to the latest restoration of the outer walls of the Opera was painted gray and the painting it a light beige. This is after the restoration in recent years.
Next lot number 131 - Sleshinsky? Just for signature.
Lots № 73,117,137 Tsvetkova? And number 31 - in general a disgrace!
