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.
Colorized from a Shorpy original. I've seen two different versions of the American Railway Express logo; one in green with red lettering, and the red diamond version here, a more obvious precursor to the Railway Express Agency which would be incorporated in 1929. Apologies if I have any of the uniform colours wrong. View full size.
