Царскосельский парк 1821—1822 часть 2 - Russian and soviet artists Русские и советские художники

The picture has something of this: tree, landscape, park, nature, sky, grass, outdoors, fall, dawn, scenic, summer, lake, house, sight, wood, light, water.
Perhaps it’s a painting of a park with a lake in the background and people on the grass in the foreground and trees on the other side of the lake.
