The Denver Post‘s plog (photo blog) recently published some 70 photos dating from 1939-1943, commissioned by the Farm Security Administration/Office of War Information. They belong to the Library of Congress and were part of an exhibit called Bound for Glory: America in Color.

You’re probably familiar with the iconic black-and-white images of farmworkers by Dorothea Lange and others, but these pictures land a new, walloping punch — because they are in color. The first modern color film wasn’t introduced until 1935 and was not widely used until some years later, making these slides a rare color record of the effects of the Depression on America’s rural and small-town residents.

And the images are somehow shocking in their intimacy in a way that their counterparts in black and white, because of the historical distance it imposes (at least for me), are not. Here are six depicting food, farming, or energy.

Children gathering potatoes on a large farm in Aroostock County, Maine, in 1940. (Child labor was not federally regulated until 1938, and farms fought for and gained exceptions to most of the age and payment rules.)
