Being Saatchi, he buys in bulk: the paintings documented here, from Albert Oehlen, Dirk Skrebber, Thomas Scheibitz, Kai Althoff, Wilhelm Sasnal and Franz Ackermann, are not just single pieces, they're elements of 10 and 15-piece portfolios. Being Saatchi, he doesn't shy away from violence, for which fans of Kai Althoff will be grateful; there are some striking pieces here.
