A large horizontal blue pencil back-view figure drawing with a coiled bun at the nape — the bun rendered with the characteristic concentric loop marks that connect this drawing to the spiral vocabulary running through the collection. The figure sits with one leg extended to the left, the foot at the composition's far left with specific toe description, while the arms extend and brace the body at the right.
The bun at the upper right is the composition's most specific element: a compact coil, the rings of the wound hair visible. It is not the elaborate tight spiral of the Spiral Crown (1154) or Spiral Bun (1135), but a more relaxed coil — the same form at a different tension.
The back below the bun is described with confident blue pencil contour: the shoulder line, the spine's ridge barely indicated, the hip mass at the composition's center. The back is clean, the form found through a single outer contour with minimal interior.
The arms extending to the right are the composition's most active elements — the bracing posture of someone supporting their weight on both hands while sitting on the ground. Both hands at the right edge are briefly described.
