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.

Our third look at that circa 1917 car wreck at Massachusetts Avenue and 21st Street N.W. in Washington. As with so many of these old glass negatives, mold is colonizing the thicker parts of the emulsion. The result is an accident scene that looks like it's been dusted with flour.

Dave, I think you got it. Other details (radiator cap, horn) match nicely. Well done.
Has anyone identified the make of this auto? I didn't see a manufacturer's logo. It seems to be right-hand drive with controls outside the cab -- probably emergency brake. That great horn could be an add-on. With the worn and slightly tattered top it probably is dated sometime earlier than 1917.
[The hubs are embossed with what looks like the word "Eagle." Or maybe "circle." There's one more photo of this car left to post. - Dave]

Below, the 1907 New Eagle, a four-cylinder car made in England.

What's that bottle for on the running board? If it were 50 years later or more, I'd say it's a fire extinguisher, or it's an NOS bottle and this heap piled up while draggin' fer pinks.
[It's acetylene gas for the headlights. - Dave]
All these early car accidents make me think surely there were carriage/wagon wrecks. Any pics of those?
[Not that I've seen. But there are plenty of newspaper accounts of "runaway teams," which seem to have been a major hazard. - Dave]
While the horn is certainly cool, it is not a Klaxon. Klaxons are electric or hand powered. This could be a Rubes horn.
