Cree takes in the artwork that she and 19 other program leaders at ART180 created to celebrate the nonprofit’s 20th year of giving young people from challenging circumstances an opportunity to express themselves through painting, sculpture, murals and other art. The anniversary exhibit opened last Friday at the organization’s Atlas Galley, 114 W. Marshall St. Work from the exhibit, titled “Twenty: ART 180 Takes the Bus,” will spend most of August touring the city on GRTC buses.
