Wow, that's like the wall next door to my home before the city made all this kind of stuff illegal, and the owner repainted, so that now everything is beautiful like in a Painting of Light.
I was mildly surprised to see quite a bit of this kind of thing when I was home. Have no idea what it might mean!
It's the end of the world, man, ads for Armageddon.
At least they're giving notice! ;-)
