The image shows a portrait of Sir Thomas Overbury. He is depicted from the waist up, seated at a desk with his head resting on his left hand and gaze directed towards the viewer. He has curly hair, closely cropped, and features a slightly upturned mustache. He wears a richly embroidered garment with a ruffled collar, typical of early 17th-century fashion. His right hand holds a quill over a partially open paper. A small inkpot is to his left. Above and to the right of the portrait is a coat of arms, and to the left is a decorative scroll identifying him. The background is ornately decorated with patterns and flourishes.
