Blek le Rat, born Xavier Prou in Boulogne-Billancourt,Paris in 1952, studied painting and architecture. His motivation being social consciousness and the desire to bring the art to the people, Blek le Rat began his artwork in Paris in 1981 greatly influencing today's graffiti and "guerilla art" movements.
Le Rat is known as the pioneer of stenciling, and often replicated by British graffiti artist Banksy. "Every time I think I’ve painted something slightly original, I find out that Blek Le Rat has done it as well, only twenty years earlier" Banksy, 2005.
Small rats sprayed the streets of Paris from 1981. It is legend when the human race will have disappeared and died out only rats will survive.
