caption: The image shows a drawing of a man in a white coat sitting on a chair, holding a hat in his hand. The man is believed to be Sir Thomas Rowlandson, as indicated by the text at the bottom of the image which reads "Sir Thomas Rowlandsson". He has a serious expression on his face, and his hands are resting on the armrests of the chair. His hair is neatly combed and his eyes are focused on something in the distance. He is wearing a long, dark coat with a high collar and a cravat around his neck.
