For the 50th anniversary of Picasso’s death the Paris museum dedicated to him invited Sophie Calle to take over the Hôtel Salé. She showcased the “succession” of her possessions, and the Drouot auction house drew up 482 lots from her belongings. The artist then imagined an Erratum identical in format to the auction catalogue, revealing the hidden history of more than 100 pieces: objects offered, exchanged, collected on her travels or inherited.
