Caricature is an art form that exaggerates features to create humorous or satirical portraits. Caricature artists use a range of techniques such as exaggeration, distortion, and symbolism to amplify certain features and create emphasis, humor, or critique. Caricatures can be personal, political, editorial, or humorous, with notable exponents including Leonardo da Vinci, Honoré Daumier, and George Cruikshank.
