caption: The image shows an old book with a drawing of a man riding a horse, with the text "Regiment de Clermont-Tonnerie, Cavalierie en Quartier à Laon" written on it. The man is wearing a long coat and a hat, and is holding a sword in one hand and a shield in the other. The horse is galloping forward, with its mane and tail flowing in the wind. The background of the image is a deep blue, with a few stars twinkling in the night sky.
