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.
San Francisco, 1966. International Days of Protest march on Market St. between Powell & Mason. Slide mount is dated August. Is the theater marquee a comment? The Woolworths at Powell & Market is now The Gap. The near buildings along Market are all gone, the area now occupied by Hallidie Plaza. I took this on 35mm Kodachrome. View full size.
