Approximately 11,000 photographic images documenting examples of architecture, landscape architecture, and urban planning in the United States and internationally between c.1865 and 1960, including some interior views showing and images of mural paintings, sculpture, and furnishings and decorative arts, and views of public sculpture. The collection includes some images of the World's Columbian Exposition (1893) in Chicago, the Louisiana Purchase Exposition (1904) in Saint Louis, the Panama-California Exposition (1915-1916) in San Diego, the Panama-Pacific International Exposition (1915) in San Francisco, the Century of Progress International Exposition (1933-193) in Chicago, and the Texas Centennial Exposition (1936) in Dallas that document the sculpture, sculptural decorations, and mural paintings at these fairs. An added component, HALIC Modern, is a growing collection of approximately 700 images that document post-World War II architecture, landscape and urban planning of sites across the United States—with a particular emphasis on Chicago and its suburbs—and, to a lesser extent, internationally.
