caption: The image shows a painting of a man in a black coat and white shirt, framed in a photo frame. The man is believed to be Sir Thomas Rowlandson, as indicated by the title of the painting. He has a serious expression on his face, and his hands are clasped in front of him. His hair is dark and his eyes are focused intently on something in the distance. He is wearing a dark coat with a white collar and cuffs, and a white shirt underneath.
