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.
Due to my Grandfather's work with Pierce Arrow, I took a stab at guessing the location. Using Google maps and some online history of the Statler Hotel I was able to match the image to Detroit's Grand Circus Park. The next guess is the date. Possibly about 1915-20. View full size.
