caption: The image shows a black and white engraving of a man with a mustache and a ruffled collar, holding a sword in his hand. The text on the paper reads "Serensissimi dvciis genva and ioannes carolus doria". The man has a serious expression on his face, and his eyes are focused intently on something in the distance. He is wearing a long, dark coat and a white shirt, and the sword he is holding is held firmly in his right hand. His facial features are detailed and his hair is neatly combed.
