Klein was a goddamn rockstar.
Well put. To be honest I haven't read too much on him yet so I didn't want to make any claims, but I can only imagine what kind of insanity he was cooking up back then. It seems like he had the collective energy of a culture about to burst into a new era, and he'd just been poking at the social tension that was building towards intense progressiveness (dead center of the 40s & 50s!). I could add a link to your comment in the Klein intro if you dont mind.
That Magritte is worth something proper I bet, find a reliable art collector/broker and see what they say.
