123Klan is a French graffiti crew, founded in 1992 by husband and wife Scien and Klor. Since 1994 the crew have also worked in graphic design, inspired by the work of Neville Brody, and started to apply it to their graffiti (and vice versa). They describe their art as ‘when street knowledge meets technology and graffiti melds with graphic design’. Dean, Sper, Skam, Meric, and Reso 1 are the other crew members.
Now residing in Montréal, Canada - 123Klan's studio has found its niche specializing in character illustration, branding, toy design, and touring the world speaking at conferences. Their client list extends to the likes of Nike, Adidas, Lamborghini, Coca Cola, Stussy, Sony, Nasdaq to name a few.
