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:
An unknown boy riding his tricycle in (mid-1930s?) San Diego. View full size.
If you ask me, one of these people is enjoying this ride more than the other. UPDATE: Well, as SilentEchoes57 has pointed out, this isn't the Giant Dipper. As the Wild Mouse had been gone for several years when I took this shot, this is probably the Jet Star, a smaller coaster ride that operated until 1991. 35mm Kodacolor 100 negative.
