caption: The image shows a drawing of a building on a piece of paper, which is part of a study for a study of the city of London. The drawing is done in black ink on a white background, and the paper is slightly crumpled, giving it a worn and aged look. The building is depicted in a realistic style, with details such as windows, balconies, and a staircase leading up to the entrance. The sky is a deep blue, with a few white clouds scattered throughout. The sun is setting in the background, casting a warm orange glow over the scene.
