{"value"=>"<p>Research files are arranged by topic, often further sub-divided by date and country of origin, and contain brochures, color prints, etchings, catalogs, postcards, sketches, research notes, drawings, articles, correspondence, clippings, blueprints and photos. Many folders are cross-referenced to other research materials. The files are particularly strong in the subject areas of architecture and costume design. Included are original English colored engravings of costumes (1815-1830), German colored costume plates from <span class=\"title\">Der Bazar</span>(1880-1898), and colored European costume prints of the 1880s. The series also contains a holographic letter from Queen Mary (1924) found in Box 14, Folder 16 about Queen Mary's Doll House and many cabinet cards and other 19th century photographs.</p>"}
