This graphic was produced by Mike Flugennock to use to promote a free concert to be held at the Washington Monument on September 24, sponsored by United for Peace and Justice called Operation Ceasefire. According to the flyer (see it on Flickr), the concert will feature the Thievery Corporation, Anti-Flag, Le Tigre, Bouncing Souls, Wayne Kramer of MC5, Head-Roc, and The Coup. See more information from the planning group.
