Double Circular Sector
A small geometric diagram of two paired circular sectors on an otherwise near-blank verso
The verso carries only a small geometric diagram of a double (paired) circular sector, lettered b a – d c. Most of the marks visible across the sheet are show-through from the densely written recto seen through the thin paper, not writing on this side.
