Groundbreaking French artist Cassandre (1901 – 1968) revitalized poster design and its psychological impact with ads intended to be seen from fast-moving vehicles. Born Adolphe Mouron Cassandre, he conceptualized a succession of posters that could be rapidly viewed to form a complete idea. He believed that an ad’s words and images must instantly evoke strong emotions and mental associations. Inspired by Cubism, his posters were very geometric and mathematically structured. Cassandre innovated several fonts, and always started his posters by first painting the text. A prolific artist, Cassandre also designed covers for Harper’s Bazaar as well as the Yves Saint Laurent logo.
