To graffiti artists, the concrete that lines the Los Angeles River is like a 52-mile long stretch of canvas. Seen as a very legitimate art form to those who create the pieces--and many of the people who admire them--the Army Corps of Engineers is constantly battling the paintings, spending millions of dollars to clean the concrete walls. Saber One, a fan artist who became famous in the global community of graffiti artists for a painting he did on the walls of the river, sees graffiti as an important part of the Los Angeles' history. It's true--some graffiti along the walls dates as early as 1913.
Below is a slideshow of ephemeral street art on the Los Angeles River and a video interview with graffiti artist, Saber One.
