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.

November 1942. "Pittsburgh, Pennsylvania (vicinity). Montour No. 4 mine of the Pittsburgh Coal Co. Mine car operating off a trolley cable." Medium-format nitrate negative by John Collier for the Office of War Information. View full size.
I read your comment because I was intrigued by the word "aptonymical". Though I haven't found a real definition for that term, I sense its meaning and when I looked up the word "Collier" I was amazed. I live in a suburb of Pittsburgh, in a state ripe with coal mining history and continued industry. Nearby is Collier Township, yet I never looked up the word! Thanks for pointing out the photographer's name. Simply amazing.
Maybe he's in administration or perhaps a safety inspector - when it's time to go into the "field" he opens the trunk, retrieves a helmet and steps into his coveralls. I would schedule my visits to the job site toward the end of the day so I could go straight home and into the shower.

Now I know.
The photographer has a perfect last name for this job.
I wonder how many mine shoots he was assigned to.
WWII has been on for almost a year. The mines must have been considered essential work places and that would bring with it deferment from the draft. I just get the feeling he's management and not labor.
I hope that trolley wire is a safe low voltage, as it's just the right height to brush against or even use as a handrail.
This boy gets bonus style points for wearing a necktie in a coal mine.
