caption: The image shows a black and white photo of a man in a military uniform, believed to be Sir Thomas Rowlandson, with a dog by his side. He is wearing a long coat and a hat, and has a stern expression on his face. His hands are clasped in front of him, and his gaze is directed towards the viewer. The dog is standing beside him, looking up at him with its ears perked up, as if it is listening intently.
