Celebrity Caricatures By Marco Calcinaro

Thus, the word "caricature" essentially means a "loaded portrait". According to caricature teacher Sam Viviano, the term refers only to depictions of real-life people, and not to cartoon fabrications of fictional characters, which do not possess objective sets of physiognomic features to draw upon for reference, or to anthropomorphic depictions of inanimate objects such as automobiles or coffee mugs. Legendary animator Walt Disney on the other hand, equated his animation to caricature, saying the hardest thing to do was find the caricature of an animal that worked best as a human-like character.
History
Some of the earliest caricatures are found in the works of Leonardo da Vinci, who actively sought people with deformities to use as models.
