About the Photos

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.

Bolling Field

The building in the background is the Army War College at Fort McNair.

Can you hear me now?

Verizon, the early years.

Acoustic Amplifiers

There still exist some of the specially constructed concrete "amplifiers" along the coast of England that were used to listen for approaching aircraft in WW2.
