Blank Verso (Invisible Before Restoration)
Void of writing or drawings; show-through of the recto's column-hoisting machines
A caption notes that this side of the leaf was invisible before restoration and carries no writing or drawings of its own. The forms seen here are show-through from the recto, where the screw-driven triangular hoist and the tall column-raising jack appear in reverse. The catalogue classes the sheet under architecture and applied arts.
