The term arises from the twentieth-century practice of featuring appealing children and young people in charitable advertisements. These figures appeared on posters to elicit public sympathy and donations for specific medical or social causes. The idiom has since detached itself from the physical medium of the poster to describe any individual serving as a quintessential representative of a particular trait or movement.
