A large pencil figure drawing with a signature at the lower right — one of the few signed figure drawings in the collection, indicating Sidney considered this work finished and significant. The figure sits facing the viewer in three-quarter view, the face with a direct, slightly confrontational gaze — the model looking back at Sidney with a quality of challenge or assertion.
The face is the most tonal element: the brow shadow, the eye socket depth, the nose modeled on both sides, the lips with their set expression. The face has genuine three-dimensionality and individual character — this is a specific person.
The body is described with the sustained tonal approach: shadow at the armpit, the waist, the raised knee. The raised knee at the composition's right creates a dynamic element that prevents the seated pose from being purely static.
At the lower left, the hand is specifically described — the fingers, the palm, the wrist. The foot below the raised knee has the characteristic toe-by-toe attention.
The signature at the lower right places this among the select group of figure drawings Sidney considered important enough to formally claim.
