Subseries Scope and Content Summary
This subseries consists of aerial photographs taken of the entire county or a large section thereof in 1939, 1940, 1950, 1956,
1960, and 1961. The 1939 set consists of 9 x 9 inch pictures; the 1950 and 1956 sets include both 9 x 9 pictures and large
prints, at least 23 x 23 inches. The 1940, 1960, and 1961 sets include only large prints. Each photograph is dated and includes
an identification number. Large photographs, or keys, which indicate how the individual aerial photographs fit together,
are available for 1939, 1950, and 1956. For 1939, the two sets of keys cover only part of the county. For 1950, six of the
seven parts of the key are available, and for 1956, all seven parts of the key are present. For 1960 and 1961, single-sheet
guides indicate the areas covered by individual photographs.
The photographs are arranged by the year taken and then in order by identification number.
