This tall and thin building forms half of James Lane and two sides have street art on it. You can see a biplane on top and the bottom has a intricately painted wooden fence alley scene. I thought that the alley scene is a pretty good job but a friend said that maybe the artists did too good of a job. The fact that it's painted very well may give it a bit of resistance to being painted over with something new and prevent the natural image rotation that usually comes with urban art. Of course, the buildings making up the lane might not be that earthquake safe. If they end up needing replacement, it sort of makes the artwork time limit argument irrelevant. It's unlikely that any new building will have wall space put aside for spray cans.
(Here's roughly the same scene, but from a slightly different angle done in 2012. Spot the differences between these two pictures.)
