A caricature is a cartoon sketch in which the more unusual or outstanding features of a person are exaggerated for comical, often satirical, effect. Sometimes, a caricature will put its subject into a specific role or show him or her with one of the tools of his or her trade. A former president who is known for his sexual infidelity might be depicted with a mistress or a prostitute. A carpenter might be shown with a hammer or a saw. Frequently, the intended result of a caricature, especially when its subject is a vain or pompous celebrity, is a deflation of his or her ego or a devaluation of his or her public image.
