Blank verso with faint show-through lines (777v)
Recorded as devoid of writing and drawings; only faint construction lines bleed through from the recto
The Ambrosiana note records this side of the leaf as invisible before restoration and devoid of writing and drawings. What remains visible are faint straight lines and an arc that appear to bleed through from the recto rather than belong to this face.

Faint show-through construction lines
Only faint marks survive on this face: a long diagonal line, several straight lines converging toward a point, and an arc near the lower centre. These read as show-through or offset from the drawing on the other side of the sheet rather than as an independent composition.
