There are thousands of billboards in Los Angeles. Billboards are highly visible and therefore are a highly sought after by graffiti artists. The downside of painting on billboards is that they get changed so often and making the work of the graffiti artist very shortly lived.
The solution is to paint on the back of billboards. The backs of many billboards are still very noticeable and are rarely cleaned.
Augs (Augor), Sage on Melrose. This billboard is especially difficult to paint since it is on top of a Winchell's donut shop that is popular with the cops.

Shatr OMG on the 110 North Freeway. This is right next to the Staples and Nokia Theater in Downtown Los Angeles. One of the most visible billboard in LA.
Same Billboard as above with new work. EAHR by Iller.
