Cadbury Caramilk "Mona Lisa"

Description: An advertisement for Cadbury Caramilk chocolates in which Leonardo Da Vinci pauses from painting the Mona Lisa to try to explain how Cadbury gets soft caramel into the center of its chocolates. As he speaks, the model for the Mona Lisa samples a Cadbury chocolate and smiles, prompting Da Vinci to urge her to hold the expression. One of the winners of the 1975 Clio Awards.
