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.
Historical color and black-and-white photos of cars and trucks from the early 20th century: Model T Ford, Packard, Cadillac, Franklin, Renault, Oldsmobile and other marques from the brass era of automobiles; tailfinned road locomotives from the 1950s and beyond.
