The Eco Art Billboard Project began in December of last year with over 20 signs around Los Angeles that have been put up. In a valient effort to almost turn the city into an open-air art gallery with the billboard's made of recycled stock and featuring original artwork is very awe-inspiring and creative. SuperTouchBlog snapped up images of two impressive pieces from the project, the first by Matt Adrian and the second that of Gomez Bueno.
