Crossover street artist Shepard Fairey is offering a tour of his Los Angeles studio and signed prints of five pro-peace screen prints in an online auction launched by charitybuzz.

Open to bidders now through Aug. 25, charitybuzz and Fairey’s latest auction benefits Robert Greenwald’s Brave New Foundation, the grassroots social-justice and economic-disparity group that employs media and volunteers to help realize “an open democratic society.”

Fairey accelerated from ’90s iconography like his “Andre the Giant Has a Posse” and “Obey” street art to become a worldwide cultural influential when he created the “Hope,” “Change” and “Progress” prints that helped President Barack Obama win the White House. For his efforts, Fairey was sued by the Associated Press, and has become a flashpoint for art controversy in the age of Photoshop.

Check out the prints available in Fairey’s auction above, and let us know in the comments section below if you think he’s an arty original or just another postmodern borrower.
