These black and white fine art images are part of a series on Chicago's unique and intricate skyscrapers. In one, rails ascend to the sky like a ladder beckoning mere mortals aboard. Another image portrays a building that looks like an airplane ready for flight. The third building is elaborately gift wrapped and tied with ribbons, and the last image displays a complementary duo of plaids.
