Bending over a large white sheet of paper somewhere between Montmartre and Saint-Germain- des-Prés, Jean-Jacques Sempé and René Goscinny give life to a laughing and mischievous little boy, the Petit Nicolas. Between camaraderie, arguments, fights, games, mischief, and punishments in spades, Nicolas lives a childhood made of joy and learning. As the story unfolds, the boy slips into the workshop of his creators, and questions them playfully. Sempé and Goscinny will tell him about their meeting, their friendship, but also their paths, their secrets and their childhood.
