Sorel works in various mediums-pen and ink, pastel, grease pencil, and watercolor-depending on whether he is drawing a political cartoon, illustrating a children's book, or creating a mural. Whatever his method, his art invariably contains wit, draftsmanship, and gestures that reveal character. Sorel has illustrated covers for Time, New York Magazine, Fortune, Atlantic, Harpers, The Nation, Forbes, The New Yorker (46), American Heritage, and The New York Times Magazine. His murals may be seen in New York at the Monkey Bar Restaurant, and at The Waverly Inn. In 2008 Knopf published The Mural at the Waverly Inn. Knopf also published Sorel's Unauthorized Portraits, a collection of his caricatures. His drawing of Frank Sinatra on the cover of Esquire in 1966 was purchased last year by the National Portrait Gallery in Washington DC.
