Pasteurizing and bottling milk at the Caswell Dairy owned and operated by E.O. Foster. His son, wearing the billed cap, is shown working with him. The photos were publicity pictures taken by WPA worker Marion Post Wolcott in October, 1940. Wolcott was working for the U.S. Farm Security Administration and Foster was an FSA borrower in a program that allowed tenant farmers to become farm owners. The photo is part of the Library of Congress Prints & Photographs Division, Washington, D.C.
