Family of migrant potato pickers in Tulelake, Siskiyou County, California. September 1939 Dorothea Lange. Interesting to come across this picture since my family's homestead was also in the 30's in this area.
Dorothea Lange (May 26, 1895 – October 11, 1965) was an influential American documentary photographer and photojournalist, best known for her Depression-era work for the Farm Security Administration (FSA). Lange's photographs humanized the consequences of the Great Depression and influenced the development of documentary photography. From: http://www.historyplace.com/unitedstates/lange/index.html
