Reverse Graffiti Project

San Francisco's Broadway tunnel is a highly traveled thoroughfare in the heart of the city. Over 20,000 cars, trucks, and motorized vehicles pass through it per day. Its walls are caked with dirt and soot, and lined with patches of paint covered graffiti from days gone by. It set the perfect canvas to create a beautiful work of art showcasing the talents of reverse graffiti artist "Moose," and the power of Green Worksplant based cleaner.
