Most of the photos on this site were extracted from reference images (high-resolution tiffs, 20 to 200 megabytes in size) from the Library of Congress research archive. (To query the database click here.) Many were digitized by LOC contractors using a Sinar studio back. They are adjusted by your webmaster for contrast and color in Photoshop before being downsized and turned into the jpegs you see here.
UPDATE: It took only a few minutes for you to pinpoint the location to Appleton, Wisconsin. Well done! This is one of the Janet & Kermy Kodachromes, labeled "Wisconsin plane trip 1962." The slide was processed in October 1962.
