Khnopff, Fernand (Belgian, 1858-1921) 4 French artists

The picture has something of this: house, vintage, sepia, architecture, building, street, antique, wall, ancient, retro, window, home, city, light, outdoors.
Perhaps it’s a painting of a large brown building with a fountain in front of it and a cloudy sky in the background with a few clouds in the sky.
