Banksy

Here is a brief list of some well known street artists…trust me I know I’m forgetting a ton.
Currently the most notorious street artist is Banksy. He is an unknown British male. Check out his site Banksy’s Website
Banksy is not one of the originals. Blek le rat was stenciling long before Banksy. He’s street art is not as well known but is of a similar caliber. Blek Le Rat’s Website
Another artist is Dolk. Dolk also uses political imagery similar to Banksys. Dolk is much darker with his art. He throws in suicides and gas masks into his works. Dolk doesn’t have a true website but a google images works fine.
Space Invader has a unique style. He creates tiled murals of retro video games and other famous pieces.
Lastly is the most well known wheat paster around Shepard Fairey aka Obey. Fairey started with a picture of Andre the Giant and has placed the image everywhere (from the streets of London to the top of New York Skyscrapers.) Obey’s Website
