The department of Wallcoverings holds over 10,000 examples and is the largest, most comprehensive survey of wallcoverings in the United States. The holdings are especially rich in examples of 19th-century French floral and natural compositions, depicting exotic landscapes, panoramas and scenic views. In Landscape Wallcoverings, Joanne Warner documents the changing attitudes towards nature in Europe and America through the depiction of landscape on wallpapers during the 18th, 19th and 20th centuries, with 19th-century production as a major focus.
