The Radical Artist

"I can't remember a time when I wasn't drawing," says Molly Crabapple. "I can't not draw. It's how I relate to the world." And Crabapple's art - her drawings, paintings and posters - have ignited various political causes, from the Occupy Movement to protests against the treatment of prisoners in Guantanamo. She tells Anne Strainchamps how art can be a political tool.
