Mad C, whose real name is Claudia Walde, was born in 1980 in Bautzen, East Germany. It was during adolescence that she began her artistic career as a graffiti artist. Graduated with two masters in graphic design, she is also the author of three books dealing with street art and graffiti published under her true identity. His paintings in acrylic and watercolor are exhibited worldwide, but one of his major works that allowed him to be recognized internationally in 2010 is the “700-Wall”: this wall, spanning 639 m², runs along the line between Berlin and Halle. This mural is certainly one of the largest ever done by one person over a period of four months.
