The phrase poster child originally referred to a child afflicted by some disease or deformity whose picture is used on posters to raise money for charitable purposes; "she was the poster child for muscular dystrophy".
However, the term is usually used metaphorically, meaning a shining example or model of its type.
See also: embodiment, epitome and archetype.
