caption: The image shows a portrait of a man in a coat, drawn on a piece of paper with a black background. The man is believed to be Sir Thomas Rowlandson, as indicated by the text at the bottom of the image. He is wearing a long coat with a high collar and cuffs, and has a serious expression on his face. His hair is short and dark, and his eyes are focused intently on something in the distance. His hands are clasped in front of him, and he has a slight smile on his lips.
