caption: The image shows a portrait of a man in a black and yellow dress, 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 black tunic with a white collar and cuffs, and a white shawl draped over his shoulders. The background is a deep blue, with a few stars twinkling in the night sky.
