That being the case, here are several images of early works by Dorothea Lange, signed and dated 1921. Images of these prints are surely not available elsewhere, so enjoy them while you can. The originals were found locally in Sept. 2009.
I'm still shocked that the Library of Congress offers free downloads of high-res negative scans of her best images. I wonder if you would like that.
Farm Security Administration documentary photography was paid for by the US taxpayers. The photographers and support personnel were employed by the US government, and thus also paid by taxpayers. That arrangement places their for-hire works into the public domain, and thus available to the public who paid for them via the Library of Congress.
But there are limits. I can download a high-resolution digital reproduction file and print my own copy. But if I were to ask the LOC to borrow the original negative for a weekend to print my own copy... ?
"When making a portrait, my approach is quite the same as when I am portraying a rock. I do not wish to impose my personality upon the sitter, but, keeping myself open to receive reactions from his own special ego, record this with nothing added: except of course when I am working professionally, when money enters in,—then for a price, I become a liar..."
— Edward Weston, Daybooks, Vol. II, February 2, 1932
