caption: The image shows a black and white drawing of a man in a suit and tie, identified as Louis Bouvard, with text written on the paper. He is wearing a black suit with a white shirt and a black bow tie, and has a serious expression on his face. His hair is neatly combed and his eyes are focused intently on something in the distance. His hands are clasped in front of him, and his posture is upright and dignified.
