In preparation for next month's opening of the Shepard Fairey: Supply and Demand, the Contemporary Arts Center (CAC) is seeking wall spaces throughout the City for the exhibition's public murals.

By February 4, the CAC is looking to find at least 30 outdoor spaces for the installations, which will consist of long-lasting – but not permanent – pasted paper and wheat paste artworks.

Submissions can be made to CAC Chief Preparator Joel Armor at and should include an image of the wall, building, or site; the address of the site; the site's approximate dimensions; and the property owner's name and contact information.

Shepard Fairey: Supply and Demand will run on levels 4 and 5 of the CAC from February 20 through August.

Best known for the 2008 presidential campaign's Barack Obama "Hope" poster, the exhibition will feature a more than 80-work retrospective of the artist, graphic designer and illustrator's 20-year career.

Fairey, who resides in Los Angeles, last had his work displayed at the CAC during the Beautiful Losers exhibition in 2004.
