The image shows a detailed engraving of an elderly man displayed in a half-body portrait. The man is positioned slightly turned to his right but faces forward, allowing the viewer to see his upper body. He has a prominent forehead, deep-set eyes, and a long, full beard with short mustaches. His hair appears to be receding and is light in color. The man is wearing a dark coat with a high collar, over a shirt that has ornate buttons running down the center. The background is minimal but framed with an oval border. Below the portrait is a detailed platform with engraved text identifying the subject as Messire Pierre Jeannin.
