The Howard Hughes Professional and Aeronautical Photographs contain black-and-white photographs of businessman and entrepreneur Howard Hughes and his companies from 1916 to 1997. The photographs primarily depict Hughes alongside his aircraft, including the XF-11 prototype reconnaissance plane and the HK-1 Hercules, better known as the "Spruce Goose" or "Flying Boat." The photographs also cover the companies owned by Hughes, including Hughes Tool Company, Hughes Aircraft Company, Hughes Electronics Corporation, and RKO Pictures.

The Elmo C. Bruner Architectural and Real Estate Appraisal Records date from 1937 to 1996 and contain architectural and appraisal records from Las Vegas, Nevada. Bruner joined A.L. Worswick’s office in 1947, taking it over following Worswick’s retirement in 1954. In 1958, Bruner formed the Las Vegas Appraisal and Finance Corporation. The bulk of the collection consists of appraisal records for residential and commercial properties in Las Vegas, Henderson, and North Las Vegas. These records provide a detailed look at the urban development of the region as well as building design, style, and neighborhood characteristics. The architectural drawings highlight the work of Worswick and Bruner, including Frazier Hall at Las Vegas High School and the original adobe administration building at McCarran Airport.
