The photograph became an icon of the Great Depression: a migrant mother with her children burying their faces in her shoulder. Katherine McIntosh was 4 years old when the photo was snapped. She said it brought shame -- and determination -- to her family.

McIntosh is the girl to the left of her mother when you look at the photograph. The picture is best known as "Migrant Mother," a black-and-white photo taken in February or March 1936 by Dorothea Lange of Florence Owens Thompson, then 32, and her children.

Lange was traveling through Nipomo, California, taking photographs of migrant farm workers for the Resettlement Administration. At the time, Thompson had seven children who worked with her in the fields.

"She asked my mother if she could take her picture -- that ... her name would never be published, but it was to help the people in the plight that we were all in, the hard times," McIntosh says.

"So mother let her take the picture, because she thought it would help."
