Photographs of the graffiti-laden Los Angeles River, all taken over the course of a single day, as indicated by the timestamp on Marcopoulos's camera. The grainy black-and-white images show a lone figure on a sandy bank among bushes and a crouching figure on a concrete riverbed covered in graffiti. The wide horizontal format is well suited to describe a functional architecture of concrete overpasses and embankments, barren environs reclaimed by the skate and graffiti communities. Handsomely produced on a mimeograph machine in a small edition.
