Ink on the final two lines of f.51v has smudged. There are remnants of wax in the lower right-hand corner of f.52r that has caused some staining to the facing page (f.51v). The wax seal is partially extant on f.52v. The letter was locked before sending and so features one horizontal and two vertical fold lines.
Parts of l.12-13 of f.52r have been underlined. A postmark has been drawn over the address on f.52v. The address has been added in the hand of Collini.
