As someone has commented on You Tube underneath the above, “Wonderful , soulful, expression of Imperial Russia from many aspects just before the Black Curtain of the war that aesthetically affects us into our era!” There are even colour photographs of that strange era in Russia before the Revolution that show the huge contrasts in wealth and also the peaceful landscape which is evoked like a distant Edwardian Summer. Serov died in 1911 having left behind masterpieces of portraiture including his own famous self-portrait. His style was realistic and is still much beloved by the Russian people.https://en.wikipedia.org/wiki/Valentin_Serov
