The book of maps has an oiled paper cover that is turned in over a paper support. The cover is worn with breaks in the surface from creases and wear. The edges are exposed and the spine covering is missing.
The book is made up of maps adhered to the facing section of each map. There are no sewing supports. The maps and creases have shifted into a concave shape in the spine and are folded into eight. There are small losses and tears where the folds meet. The paper support is slightly discolored overall due to aging. The image and the text are brush applied with Korean muck and watercolors.
The volume was surface cleaned with a natural rubber sponge and a soft brush. The maps were humidified with water vapour through Gore-Tex and flattened between blotters under moderate weight. The tears and losses to the maps were mended with acrylic-toned mulberry papers adhered with wheat starch paste. The mends were toned in-situ with watercolors where necessary. The peeling of the surface of the cover was adhered to the surface with wheat starch paste and the losses of the surface on the cover were mended with mulberry papers adhered wheat starch paste.
The cover was consolidated with wheat starch paste and burnished on the repaired area with bone folder to match the original.
