I finally got around to seeing Tim Samuelson’s “Wright’s Roots” exhibit, currently set up at Expo 72. I won’t try to reconstruct the displays here for you —it’s an enjoyable little demitasse of an exhibit, giving a delicious, bracing jolt of history about Frank Lloyd Wright’s early years, his tutelage under Sullivan, and the development of his own inimitable style. perfect for a lunchtime visit. See it before it closes next week. I snapped a few pictures. Enjoy.
