Shepard Fairey, the artist best known for his Barack Obama "Hope" poster in 2008, is leaving his mark near Chicago's lakefront.

As part of the Navy Pier Walk 2011 art exhibition, Fairey has created a giant poster mural for the Lake Shore Drive viaduct at Grand Avenue. Measuring 130 by 10 feet, the "Obey" mural features a string of album-coverlike works. It is Fairey's first such installation in Chicago and will remain at the site through October.

The largest outdoor installation of its kind in the country, Navy Pier Walk 2011 opens July 1, after a five-year hiatus.

Fairey's mural will anchor the display. It is printed on standard copy paper using an oversize blueprint printer and applied to the surface of the viaduct with standard wallpaper glue, exhibition organizers said.

A water-based finish was applied to the artwork to protect against weather and graffiti. The installation was completed last week.

"As people examine Shepard Fairey's work on their way to Navy Pier or the lakefront, I hope they will enjoy seeing it, will think about the issues it raises and also gain a new appreciation of the transformative power of public art," said Joseph Tabet, curator of the walk.
