A couple of images from a city known as "The Star of the West"...
When you walk into this alley, you immediately notice that there seems to be lots of art that has been painted over. It was probably done by the store/building owners, but certain things have been spared this wanton rolling. I wonder if it's some type of Tagger/Stencil Artist turf-war? Regardless, it's too bad to lose the time that was put into those pieces. If you look closely, you can still see quite a bit of work on some of the walls. Artists have taken the painted-over areas as an invitation to start again, and it seems to be kind of a natural process of rejuvination. I've included pics of some of my favourites (I'm sure that you'll recognize the burly kid in glasses).
The 'cleaner' obviously agreed with the above stencil, and decided just repaint AROUND it...
This angle shows some of the stuff that has not been painted over. I especially like the pills in the top right - they were everywhere, including the ground (if you look closely), and were really well done.
It shows kind of a neat effect on different surfaces.
