Leonetto Cappiello (1875-1942) was an Italian poster artist who revolutionized the art of advertising in the early 20th century. Born in Livorno, Italy, Cappiello moved to Paris in 1898 and began his career as a caricaturist for newspapers and magazines. He soon turned his attention to poster design, creating bold, colorful images that captured the attention of the public and helped to sell products ranging from cigarettes to bicycles. Cappiello's style was characterized by his use of bright colors, exaggerated forms, and witty slogans, and his posters became some of the most recognizable and iconic images of the era. He worked for many of the leading companies of the time, including Campari, Pirelli, and Fernet-Branca, and his work was exhibited in galleries and museums around the world. Despite his success, Cappiello remained humble and dedicated to his craft, and his legacy as one of the greatest poster artists of all time continues to inspire artists and designers today.
