The Gunpowder Magazine, Hyde Park Paul Sandby (1725-1809)

The picture has something of this: tree, landscape, nature, outdoors, fall, wood, park, sky, grass, rural, leaf, branch, dawn, countryside, winter, environment, fair weather, country.
Perhaps it’s a painting of a horse and a man in a field next to a tree with a building in the background and a fence in the foreground.
