caption: The image shows a page from a book with a drawing of a man's face on it. The paper is filled with text and drawings, likely from Leonardo da Vinci's famous work. The man in the drawing has a serious expression on his face, and his eyes are focused intently on something in the distance. His hair is dark and his skin is a light shade of brown. He is wearing a white shirt and dark trousers, and he is standing in front of a white background.
