The image shows a portrait of a person with their upper body visible, centered in an oval frame. The individual sits facing the camera directly, with their facial expression showing deep lines and furrows, particularly on the forehead and around the eyes. They have sparse hair that is combed back. Their clothing consists of a light-colored shirt with an open collar. There are two hands visible in the frame; one is adjusting a wire attached to the individual's face, while the other holds an object at their cheek, possibly also connected to wires. There is no jewelry seen on the person. The background appears plain and unfocused, emphasizing the centered figure.
