Boy resting in an extensive summer landscape Nikolai Petrovich Bogdanov-Belsky (1868-1945)

The picture has something of this: nature, outdoors, summer, leisure, grass, people, sky, park, landscape, rock, hayfield, outside, vacation, happiness, lifestyle, portrait.
Perhaps it’s a painting of a man sitting on a rock in a field of grass and wildflowers, with a view of a valley in the distance.
