caption: The image shows a painting of a man in a red uniform, believed to be Sir Thomas Rowlandson, painted by Sir Joshua Reynolds. The man is standing in a regal pose, with his hands clasped in front of him and a stern expression on his face. His hair is dark and his clothing is a deep red, with gold buttons and a high collar. He is wearing a black belt with a gold buckle, and his hands are clasped together in a dignified manner.
