The conservation lab received, from the American Art Museum/National Portrait Gallery Library, a first edition of the first Bauhaus exhibition catalog: Staatliches Bauhaus, Weimar, 1919-1923. In addition to being a rare copy of this catalog, it is inscribed to the painter Werner Drewes by his Bauhaus teacher, Wassily Kandinsky. The book was in disrepair with the covers detached. A spine “replacement” fashioned out of a piece of electrical tape had left tape residue on the Herbert Bayer designed cover. Additionally, the paper used for the catalog was highly acidic and discolored and the acidic clay coated plates were chipping.
