Both volumes are hardbound in their original green cloth covers with gilt titling on the spines.

The map has some offsetting, and a bit of insect damage in the upper margin, just reaching the neatline. There are several fold splits, some repaired with archival tape on verso, and some extraneous creasing. Text pages are generally very good with an occasional spot, and some toning along the edges. All signatures are tight. The covers are a bit rubbed with minor shelf wear.
