Interesting stuff. Do you have links to material that delves more into the differences in how O'Keeffe and Pollack were promoted? The JSTOR article makes it sound like both were promoted by the U.S. as anti-Soviet propaganda, but in O'Keeffe's case before the formation of the CIA.
Was her work intentionally suppressed by the CIA, or was this a luck-of-the draw timing issue?
(I assume "sexism" is in there somewhere, but I'm hoping for more clarity on what the CIA specifically did.)
