I stumbled upon this by accident this past week as I drove through Downtown LA past the 3 giant buildings home to the American Apparel factory. Sometime at the end of last year, artist RETNA was tasked with covering the entire facade of the American Apparel factory facing 7th Street. The result is this finished piece that looks amazing in person. I'm not sure if this is RETNA's biggest piece yet, but if it isn't, I'd guess that it's pretty damn close.
Check it out in person at the corner of 7th Street and S. Alameda.
