I love that one! When I went to DC about a year back to visit my ex, I actually saw one of the Human Condition paintings up close and personal (Magritte painted a series of them), along with one other painting and two statues. Since she broke my heart, that's actually the only thing I care to remember about the trip. haha. I also saw a Yves Tanguy there, who is quite reminiscent of Dali in the colors he used. Question: do you think Dali is overrated? I did, until I saw two of his paintings in person... the man was a technical genius. I couldn't even see a damn brushstroke!
EDIT: Thought I'd mention my favorite surrealist painting: Time Transfixed, by Magritte. Even seen it? It's creepy in its simplicity, but that's why I love it.
