The image shows a portrait of a man from the shoulders up, captured in a three-quarter view. He has distinct facial features with a prominent mustache and an oval face. His hair is full, wavy, and long, cascading down to his shoulders. The man is dressed in a dark jacket or coat over a white shirt. There is no visible jewelry or objects being held. The background features an oval frame within the artwork set against a textured, intricately-hatched pattern. An inscription at the bottom of the image identifies the person as Gulielmi Dobson.
