Mr Brainwash's son Hijack reveals first solo collection The first exhibition of works by Hijack, son of street artist Mr Brainwash, has opened in London. In 2010, Bristol-based street artist Banksy released documentary Exit Through the Gift Shop, which charted the rise of French filmmaker-turned street artist Thierry Guetta. Guetta, living in LA at the time, adopted the name Mr Brainwash and shot to fame, selling works of graffiti art for vast sums. Picture: Melanie Pinetta
