Graffiti aus Berlin

While in Berlin, I took a lot of photos of graffiti that I found amusing or impressive. Here's an example of the former, seen on Oranienstr. in Kreuzberg. (This is arguably my favorite street in the world.)

I assume this sort of graffiti is done with a stencil, but I always wonder if they're made by hand or mass produced. Is there some magical shop where you can buy snarky graffiti stencils? Or do you have to order them online?

Now, I'm not a vandalism kind of girl, but I do find myself sort of itching to come up with a brilliant idea, and to take to the street with my home-made stencil, a can of spray paint, and no fear whatsoever. But maybe I'm just feeling a touch rebellious.

Also, why don't you see this often in the States?
