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.

"Municipal Building, Southern Railway, and Post Office Department, from the Willard Hotel roof." An ethereal, almost spectral view of Pennsylvania Avenue at 14th Street N.W. in Washington circa 1921, with the Old Post Office tower at left. National Photo Company Collection glass negative. View full size.
You can see from the image below that the center building in the old image is gone. The building on the right side still exists but the road was changed and there is no property in front of it. The Old Post Office is preserved and in beautiful shape.
Really enjoy all of the pictures; I do notice that it always looks cloudy in the sky but yet there are clearly shadows. Is is something to do with the development or age of the picture?
This is another one of those shots that's going to have me looking at it every time I log on, starting with surveyor in the lower left. There appears to be flagpoles on top of the buildings (or are they lightning rods?). I guess it's early a.m. and the flag raisers haven't come in yet, or it might be a non-work day.
