poplar. 1887 Apollinaris M. Vasnetsov (1856-1933)

The picture has something of this: tree, landscape, nature, sky, outdoors, dawn, water, mountain, people, light, cypress, rock, sunset, park, valley, scenic, hill, fog.
Perhaps it’s a painting of a group of people sitting on a hill next to a tree and a body of water with birds flying in the sky in the background.
