This subseries comprises groups of photographs, each group obtained from a single source, kept together in order to preserve their context. The subseries contains three such collections.

The W. A. Sloan collection was found in an envelope from W. A. Sloan, 159 N. Evergreen, Ventura, California, addressed to Roy W. Judd, 4602 N. Laurens Ave., Baldwin Park, California. The photographs date from the period 1910-1912 and primarily concern the aviator Arch Hoxsey (d. 1910); other photographs relate to the Belmont Park Aviation Meet, October 1910, while the remaining are unidentified.

The Newswire company photograph collection was found in the basement of Mabel Shaw Bridges Auditorium in May 1962. It consists of photographs taken by photographic news agencies, in particular International News Photos and International Newsreel. The photographs date from 1918 through 1938, with the majority dating from January 1930 through February 1931; they are arranged chronologically. They concern the major aviation events and leading aviators-with special emphasis on female aviators-of the time. The events include the launch of the Dornier DO-X Flying Shark seaplane; the first non-stop airplane crossing from Paris to New York, by Dieudonne Coste and Maurice Bellonte; the transatlantic flight from Italy to Brazil led by Italian Air Minister General Italo Balbo; the 1930 US visit of Mrs. J. M. Keith-Miller; and the 1931 Schneider Cup race at Calshot, Great Britain. The aviators include Jimmy Angel, Florence Lowe ("Pancho") Barnes, the Hon. Mrs. Victor Bruce, Juanita Burns, Marga von Etzdorf, Frank Hawks, Lady Drummond Hay, Mike Murphy, and "Bobby" Trout and Edna May Cooper. The photographs include several of couples who were married in airplanes aloft. Other photographs depict contemporary politicians, socialites, and film stars and starlets alighting from or ascending into airplanes.

Two panoramic photographs were found in the basement of Honnold Library in 2010. One depicts the formal reception for flyers from the USSR held by the Los Angeles city authorities and Chamber of Commerce in 1937; the other documents the 26th annual convention of the American Legion, Department of California, in Los Angeles in 1944.
