I managed to steal a couple of hours to walk around Chicago yesterday afternoon. Within about six blocks of Dearborn Street I saw a 50 ft Picasso sculpture, a 40 ft Miro, the world’s tallest church, a ten-ton Dubuffet sculpture, Mies Van der Rohe’s Federal Center Complex and a handful of very interesting skyscrapers including the sweeping Chase Tower (formerly Bank One Plaza).

My little Canon Powershot can’t do any of these buildings justice (hence the links above). Taking this photograph of the 3,000 square foot Chagall mosaic Four Seasons at the foot of Chase Tower seemed easy by comparison, and was made all the more rewarding when I noticed this amusing detail below.
