Blank verso of the building-plan sheet
No original marks; the recto's ground plan shows through the paper
This side of the leaf carries no original writing or drawing. The three-room ground plan drawn on the recto shows through the thin paper as a faint mirror image, together with the straight stair at one end. The e-Leo note records that the leaf was invisible before restoration.

Blank verso with recto plan showing through
No original marks are present on this side. The building plan from the recto — three rooms in a row with a stair at one end — is faintly visible in reverse where it shows through the paper. The archive classifies the sheet under geometry and architecture.
