caption: The image shows a painting of a man in a black coat and white shirt, with grey hair, standing in front of a wall. He is believed to be Sir Thomas Rowlandson, as indicated by the text at the bottom of the painting. He has a serious expression on his face, and his hands are clasped in his lapels. His hair is neatly combed and his eyes are focused intently on something in the distance. The wall behind him is plain and white, and the painting is framed in a simple black frame.
