Near my house is a vacant building. The very courteous street artists in my area use it as their canvas. I say courteous because they leave the other buildings alone. I love seeing the new stuff they come up with and this most recent poster kinda blew me away.

The time it took to put a blue wash over a map and silkscreen/stencil it then slap it on a building shows some serious dedication. That blue jumps out at you from down the street.

A brief google search didn't turn up anything for "Future Voxx" in my area but I can appreciate his/her style.
Here is a close up to see the map of San Francisco it was printed on.

Does anyone else have some exceptional examples of street art? I'd love to see them.
