caption: The image shows an open book with a drawing of a man with a beard and a hat on it. The man is believed to be Sir Thomas Rowlandson, as indicated by the title of the book, "Sir Thomas Rowlandsson". He is wearing a long robe and a turban, and has a serious expression on his face. His hair is long and dark, and his eyes are focused intently on something in the distance. His hands are clasped in front of him, and he is standing in a contemplative pose.
