This shot was taken less than a year after the Sears Tower (now called the Willis Tower) was completed in 1973. I shot it looking south toward downtown from the Wilson El platform. The Sears Tower was the tallest building in the world at the time and all of Chicago was buzzing about it. It symbolized the dynamism of a “City that worked” as Mayor Daley was fond of saying. A revolutionary bundled-tube design enabled it to rise twice as high as anything around it. On most days in that era, haze concealed the skyline, but this was an exceptionally clear day. A ribbon of rail connected two very different worlds – Uptown and Downtown.
