The series contains 32 black and white prints made by photographer Ernst Haas, possibly between 1948 and 1952, for the Economic Cooperation Administration (ECA), the administrative arm of the Marshall Plan. The photographs appear to document economic development, shipping, and the lives of black and white merchant seamen in Marseille, France. They include portraits of workers at work, in cafes and at home with their families, images of ports, ships, a railroad yard, building construction, post-war housing developments, and signs, political posters and graffiti in French.
