caption: The image shows a portrait of a young boy in a blue coat, painted by Sir Thomas Rowlandson. The painting is set against a white background, and the boy is looking directly at the viewer with a gentle expression. He is wearing a navy blue coat with a white collar and cuffs, and his hands are clasped in front of him. His hair is dark and his eyes are a deep brown. He has a slight smile on his face, giving the painting a warm and inviting feel.
