A tightly cropped pencil study of the hip and buttock zone — the most closely focused body-part study in the collection after Work 1530's two-foot study. The composition crops the body at the hip on all sides: the leg descends from the upper left and upper right of the paper, the buttock curve fills the center as a smooth rounded form, a brief tonal shadow mark at the buttock's inner crease providing the form's defining depth. At the upper left and left side, brief crosshatch marks describe the hip's outer surface and the leg's inner thigh area.
The near-square 9 by 8.25 format suits the subject: the buttock occupies the center of the composition in both its horizontal and vertical aspects, the cropping tight enough that the form reads as a study of volume rather than as part of a figure. This kind of close cropping — treating a body zone as an autonomous formal subject — connects to the academic tradition of the detail study, where specific body parts are observed in isolation to understand their particular form.
The soft pencil marks describe the rounded surface with tonal gradation rather than hard contour: the buttock curve is described by the shadow at the inner crease rather than by an outer line, the form emerging from tone rather than from edge. This tonal approach differs from the contour-first methods of most figure drawings in the collection and suggests a sustained observational attention to the body's surface as a sculptural form.
