Leonetto Cappiello (1875 – 1942), was a master of poster art design and painting with a significant portion of his life dedicated to his craft in Paris.

Often hailed as 'the father of modern advertising,' Cappiello revolutionized the realm of poster design. The usual artistic finesse seen in the advertising posters of the time, as attributed to artists like Jules Chéret, Alfred Choubrac, and Hugo D'Alesi, experienced a shift.

Cappiello, along with other emerging artists, approached the art form in a dramatically different manner. His groundbreaking technique of highlighting bold figures against stark black backgrounds was a departure from the established norms, setting a new precedent in poster artistry.
