He is one of the greatest living cartoonists. Jean-Jacques Sempé has been producing cartoons and illustrations since the 1950s. I have many of his books. Phaidon released a series of books some years ago. These are wonderfully produced and well worth seeking out. Here's a small sample of his work to inspire your day.
