Originally from Wales but now living in Sheffield, England, artist Phlegm is known for his self-published comics and amazing street art designs. Many of the characters that he paints on the walls of Sheffield originate from his comics. Much of his art work is illustration-based and therefore lacks the true graffiti-style lettering.
Below is a sample of his incredible artwork, if you wish to see more check out his own site.
