Wikipedia, The Free Encyclopedia:
Leonetto Cappiello (1875-1942) was an Italian poster art designer who lived in Paris. He started as a caricaturist illustrating in journals like Le Rire, Le Cri de Paris, Le Sourire, L'Assiette au Beurre, La Baionnette, Femina, and others.

Cappiello made his name during the poster boom period (c. 1900), with designs similar to those of Jules Chéret. He redesigned the fin-de-siècle pictures into images more relevant to the faster pace of the 20th century and after WW1 Cappiello abandoned caricature illustration and exclusively devoted himself to the production of posters.

Cappiello and Suzanne Meyer married in 1901.
