Forgive me if any of these photos have been posted before but I just discovered there is a fantastic searchable archive of photos from the Farm Security Administration (high-res files are available). Overview:
http://www.loc.gov/pictures/collection/fsa/"The photographs in the Farm Security Administration - Office of War Information Photograph Collection form an extensive pictorial record of American life between 1935 and 1944.

Stryker, who guided the effort in a succession of government agencies: the Resettlement Administration (1935-1937), the Farm Security Administration (1937-1942), and the Office of War Information (1942-1944). The collection also includes photographs acquired from other governmental and non-governmental sources, including the News Bureau at the Offices of Emergency Management (OEM), various branches of the military, and industrial corporations."
