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.
The caption card for this one just says "Post Office." Thanks to our commenters we now know that the building with the statue is the Our Lady of Lourdes School at 468 West 143rd Street in New York circa 1914. 8 x 10 glass negative, George Grantham Bain Collection.
