If there is a lesson in the work of the British artist Paul Curtis (aka "Moose"), it would be that the world is a mess. Curtis's signature technique is cleaning. He strips away years of accumulated soot, dust, dirt, and atmospheric detritus to make pieces like these, which were part of a celebration of street art. He also creates promotions for not-for-profits like Greenpeace and commissions for brands such as Xbox and Clorox's GreenWorks.
Curtis often wonders if his corporate clients see the grim humor in hiring him. "You're encouraging commercialism using a process that reminds people of pollution, which is partly the result of overconsumerism," he says. He adds that he recently rejected an oil company, thinking it was too ironic "that people would ask me to write their name in the dirt they made."
When Curtis puts his brush down, his commentary has only begun: Within days, the patterns begin to fade as the pollution reclaims its territory, a statement about how hard it is to clean things up and how easy it is to mess them up again.
