In LA this weekend and found some cool paste-ups and stencils. I have been following a few street art artist and blogs for a while. Shepard Fairey and Banksy are two of the most popular ones. Check out Exit Through the Gift Shop it is a great documentary about street art that will make you want to create your own art, or hate art and never want to do any type of art ever again.
This one was done by Shepard Fairey - obeygiant.com
Here is the Obey giant on the back of a billboard.
These are some random ones on the side of the building.
