Yep. You read the title right. Graffiti. On a Palestine Wall. Prepare to be amazed. And in awe/jealousy at the ingenuity of them. :P
The majority of the pics are from the same creator, a British street artist named Banksy. From all of the pics that I've seen he's done, he's really good. And I'm totally jealous of his creativity. XD
Check out his work at his website here.
