A glass of cognac turns into waves of liquid sunshine in Leonetto Cappiello’s “Cognac Monnet.” The Italian Cappiello (1875 – 1942) was a self-taught artist who cleverly melded products with fun, flamboyant images to effectively modernize advertising. Formerly a caricaturist, Cappiello created almost 1,000 revolutionary posters in 40 years. A leader of the Art Deco movement, Cappiello is known as the father of the modern poster. His groundbreaking techniques are still a foundation of today’s advertising.
