The image shows a portrait of a man depicted from the waist up, seated in a chair, turned slightly to his right. His left arm is resting on a surface, which appears to be a table. The man has short, neatly combed hair slightly parted to the side, and his facial features are defined with a sharp nose and a focused gaze directed towards the right. He is dressed in a formal suit comprised of a jacket, waistcoat, and tie, all rendered in a monochrome, sketch-like style. Behind him is a bookcase filled with books. The background is filled with hatch-like markings, contributing to the textured appearance of the piece. The artist's signature, "Muirhead Bone," is visible near the bottom right corner of the image.
