In 2003, Charles Saatchi opened the new Saatchi Gallery, for his vision of radical, ground-breaking British art in a venue that is accessible to the widest public. 100 is the book that will mark the occasion with one hundred works that Saatchi believes made a difference to the perception of British art. The work of 27 artists has been chosen from Saatchi's collection and of course the selection includes the shark and the sheep in formaldehyde, the head made of blood, and Tracey's bed.
