The U.S. Geological Survey's (USGS) EROS Data Center will begin distributing historical aerial photography in digital format on September 3, 2004. The photos come from an archive of over 8,000,000 frames acquired between the 1930's and 1970's and used to produce 1:24,000 scale USGS topographic quadrangle maps. After this release USGS will no longer distribute these photos in hard-copy format.
Sample images can be seen at
USGS Historical Aerial Photos Sample Page.
