This collection of historical imagery of areas in Los Angeles and surrounding counties dates back to the 1930s and 1940s (1927 to 1947). The Watson collection came to the Library as part of the gift from the Teledyne Foundation in 1986, and includes imagery in print and transparent film formats as well as postcard images and advertising stills. Most of the Watson aerial photography is large scale (greater than 1:10,000) and primarily covers particular locations in Los Angeles County, as well as a few locations in Orange, Riverside, San Bernardino, San Diego, Santa Barbara, and Ventura Counties.
