My late 70's Fuji Featherweight is nowhere to be found, but vintage bmx's museum has some cool pics of early bmx bikes. For really early stuff, go to the previously linked American Bicycle Museum (Still no Huffy Paydirt?)
Interesting findings in art, technology, culture, and the ever-astonishing strangeness of the human condition. Updated (mostly) daily for years and years and years from in and around Philadelphia, PA.
