It looks like it's from a 1964 article in LIFE about poverty in rural Appalachia.

The extraordinary 12-page feature for the Jan. 31, 1964, issue of LIFE, titled “The Valley of Poverty” one of the very first substantive reports in any American publication on President Lyndon Johnson’s nascent War on Poverty.

At the time, LIFE was arguably the most influential weekly magazine in the country, and without doubt the most widely read magazine anywhere to regularly publish major photo essays by the world’s premier photojournalists. In that light, LIFE was in a unique position in the early days of Johnson’s administration to not merely tell but to show its readers what was at stake, and what the challenges were, as the new president’s “Great Society” got under way.

“The Valley of Poverty,” illustrated with some of the most powerful and intimate photographs of Dominis’ career, served (and still serves today) as an indictment of a wealthy nation’s indifference.
