caption: The image shows an open book with a drawing of two men on horseback, one of whom is a cavalryman. The cavalryman is wearing a full suit of armor, including a helmet, breastplate, and gauntlets, and is holding a sword in one hand and a shield in the other. The other man is standing beside him, looking on with a stern expression. The background of the drawing is a landscape of rolling hills and a bright blue sky.
