The image is an engraving of a man facing forward and slightly turned to his left. He has a smooth forehead, a well-defined nose, and slightly smiling lips. His hair is styled in a traditional 18th-century manner, with full, curly hair around his face. He is dressed in a formal jacket, buttoned-up vest, and a cravat. The background features an oval frame within a rectangular border, with an engraved nameplate below stating “J.J. ROUSSEAU.” The engraving is monochrome with detailed line work for shading and texture.
