Early career and influence.
Blek began his artwork in 1981, painting stencils of rats on the walls of Parisian streets. He described the rat as "the only free animal in the city", and one which "spreads the plague everywhere, just like street art". His name comes from the comic book "Blek le Roc", using "rat" as an anagram for "art".
