The Benjamin and Gladys Thomas Air Photos Archives are a collection of aerial photographs—approximately 130,000 negatives
on glass and film and over 80,000 prints—that along with other related documents and objects were donated to the UCLA Department
of Geography in the 1960s. The archives are comprised of three major collections of oblique, or angled, views (as opposed
to straight-down vertical views), covering the years 1918-1972, including images from several national and local aerial survey
companies - Fairchild Aerial Surveys (1921-1965), Spence Air Photos (1918-1972), and William Cross Air Photo (1918-1924).
80,000+ prints, 130,000+ negatives; 7,000 lantern slides; approximately 70 linear feet
