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.) Most 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.

July 1940. "Under the elevated railway, Chicago, Illinois." 35mm nitrate negative by John Vachon for the Resettlement Administration. View full size.
If the Chicago Daily Tribune from June 2, 1942, is accurate, this place was at 53 West Van Buren.
The building's long gone by now (I certainly don't remember anything like it), but it would have been under what is now the Library/State/Van Buren Stop.
