Cartoonist and illustrator Phlegm is well known for his self-published comics and amazing graffiti/street art. Phlegm uses colored spray paint as well as black Indian ink to tie his walls and comics together. His graffiti art on huge walls, mostly in the United Kingdom, has become a part of city architecture.
