Curated by the influential artist's granddaughter, Ms Diana Widmaier Picasso, Assouline's 'Pablo Picasso: The Impossible Collection' dives deep beyond Cubism and the iconic 'Guernica' to include his less well-known paintings, sculptures and photographs, which all played a role in his defining his oeuvre. This sizeable hardback is hand-bound, contains 100 unique works and comes in a linen clamshell case.
