 | | About 1924 Virgil Kauffman of Yardley, PA, a former WWI aviator in France, began to shoot aerial photographs for the Aero Service Corporation, which he soon acquired, in 1927. |
 | | He ultimately assembled more than 20,000 photographs, and after he sold the company in 1961, these were stored in a Bucks County barn. |
 | | An overlapping collection was acquired by the Free Library of Philadelphia, this of aerial views, but in the form of large-format prints, both from the Aero Service Survey Company and the Dallin Aerial Photograph Company. |
