Leonetto Cappiello is associated with the art nouveau movement. He was born in Italy and lived in Paris and is considered the father of modern advertising because of his design ability with posters. Cappiello had the ability to create a creature, that had nothing to do with the product, and yet somehow it all worked in his poster design. One of the first posters Cappiello made for a merchant product was Amandines de provence in 1900.
In 1906 Cappiello did a poster for Maurin Quina featuring this green devil creature.
Isolabella is a poster for a vintage french liquor that Cappiello did in 1910.
