Abstract:A. M. Cassandre from France is a famous commercial poster designer in the period of “Art Deco”. He was good at reflecting the rationality of artistic works with simple geometric figures and realignment. He was adept in creating pictures full of tension by joining and parting the combination of lines. He performed well in rendering the exaggerated three-dimensional spaces with unique composition perspectives and contrast technique. His commercial posters were products of the times but with a far-reaching value, which is a standard of graphic design profession up to now.
