Faint pen outline covering the page (invisible before restoration)
A few large perimeter lines, too pale to identify with certainty
This verso, invisible before restoration, carries only a faint pen drawing reduced to a few perimeter lines that nonetheless span almost the whole page. A large semicircular arc runs across the upper sheet and a broad oval sits at the center, with pale rectilinear framing below. The lines are too faint for the subject to be identified securely.

Large perimeter outline across the page
A semicircular arc spans the top of the sheet above a broad ellipse, with faint straight framing lines below. The few outlines enclose almost the whole page, reading like a large plan or elevation. The drawing is too pale for its subject to be read with confidence.
