Cut into two pieces. Mounted on cloth- bound and cropped- disbound and silked by subsequent owners. Cleaned after removal of backings 1999; some fill remains. Sheathed in mylar. May be imperfect; Erskine's index states "3 pieces & [1] D[itt]o". Includes texts (severely faded). In pencil on recto: "No 37". In ink on verso: "No 37"- "No 37 1st".
