After going to a talk last month (June 21) that gave a very nice overview of the show, I finally got around to seeing it. Magritte did some very famous images, and some remain quite striking even now. However seeing them clumped together like this is a bit much; he seems to have a limited repertoire of objects (female torso, euphonium, bowler hats, ...) and to see them replicated across works is disillusioning. Taking a quick look at Google just now, it seems there were plenty more of his works that aren't at the Art Institute of Chicago presently. Anyway, glad I went. Thanks again to Pete R. for the membership.
I also tried to look at the Mexican political prints but at some point my brain exploded. There's a lot of juvenalia. I'll head back later in the week.
