"A Little A.M. in the pm"

Adolphe Mouron Cassandre (24 January 1901 – 17 June 1968), is probably on of the most influenential and most copied Graphic Designers of the 20th Century. He is most famously known for his poster designs during the 20's and 30's (before entering WWII).  As a designer,Cassandre developed the following typefaces  Bifur in 1929, the sans serif Acier Noir  in 1935, and in 1937 an all-purpose font called Peignot. He also designed the Yves Saint Laurent logo.  Tragically, Cassandre suffered from despression in his later years and committed suicide.
