Being the property of the citizens of the United States, I always thought one could buy a print from the National Archives but I've never actually looked into it. There's an image by Russell Lee of women plastering an adobe building in Chamisal, NM in 1940. I'd like a print of that.
Also, I can't recommend enough "The Worst Hard Times".
I photograph things to see what things look like photographed.
