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.
Vintage photos of:

I don't know what I.A.S. stands for, but student clubs and societies associated with their majors generally sponsored floats. My brother's 35mm Ektachrome slide. View full size.
