This photograph was in an exhibition that I held in the city in 2004 called "340 Degree View" when I was living in Chicago. A real colour piece - perfect for a contrast wall or as a strong focal point in a room.
I love this one as either a Framed Fine Artt Print or an UltraHD Glossy Acrylic.
The Willis Tower (formally and informally: Sears Tower, its name until 2009) is a 110-story, 1,450-foot (442.1 m) skyscraper in Chicago. At completion in 1973, it surpassed the World Trade Center in New York City to become the tallest building in the world, a title that it held for nearly 25 years; it was also the tallest building in the Western Hemisphere for 41 years until the new One World Trade Center surpassed it in 2013.
