Editorial cartoons, evolving from the art of caricature, normally appear on the editorial or Op-Ed pages of American newspapers. Generally single-panel drawings with some text, they provide entertainment along with political commentary since the central characters usually caricature actual people and issues. Prominent modern editorial cartoonists include Patrick Oliphant, Signe Wilkinson and Garry Trudeau (famous for Doonesbury, a “political cartoon” in comic-strip format). The Pulitzer Prize for editorial cartooning has existed since 1922.
