Thanks to Warren V for sending this photo of a mural in an out-of-the-way spot:
Warren wrote “I spotted it today (June 1, 2011) on a warehouse located across the street from Roma Imports 627 S. Vine. I'm not sure of the actual address of the warehouse.’
Thanks again to Warren and everyone else (including you?!) who send photos of mural discoveries. Even though I have another 150 or 200 that I haven't had time to post yet, we're always glad to have more.
