A green chalk back-view figure drawing — the figure seen from directly behind, seated, the back broad and the bun at the crown drawn with a spiral-coil mark that echoes the blue pencil spiral bun (1135). In green chalk rather than blue pencil, against a warm cream paper, the spiral bun reads differently — warmer, more botanical — but the same essential form is present: Sidney's coiled ring mark found in a model's hair.
The back is described with generous curves: the outer contour tracing the shoulder-to-hip sweep in a single confident arc on each side, the interior nearly empty. The hip at the lower left is the most rounded element — a large single curve that contains the sitting mass.
At the lower right, the hand and foot — described in more detail than the back itself — provide the human specificity that the broad form above has stripped away. This is the recurring strategy in Sidney's back-view drawings: the back as pure form, the extremities as individual presence.
The green chalk on cream paper gives the body its characteristic botanical quality — this is a figure that might be a plant, or a hill, before it resolves into a person.
