From the Charles W. Cushman archives.
Charles Weever Cushman, amateur photographer and Indiana University alumnus, bequeathed approximately 14,500 Kodachrome color slides to his alma mater. The photographs in this collection bridge a thirty-two year span from 1938 to 1969, during which time he extensively documented the United States as well as other countries.The archives can be browsed by subject. I've just skimmed a few categories, but I'm impressed. Try Human curiosities, markets, drums, tramps, and hippies. (Via Save Vs. Death)
