there is plenty to talk about in this rich period mid1930s- mid1950s: modern designstars, piet zwart (master of de stijl), piet mondrian's contribution to modern design, the one and only master of preWWII elegance, a. cassandre, ladislav sutnar (the neue typographie standardizer), herb lubalin (the laconic master of positive/negative), the avangardist ted mcknight koffer, the exquisite moods of cipe pineles, saul bass' groundbreaking collaborations with o. preminger and a. hitchcock, the inimitable alvin lustig. then we have WWII posters (both sides of the war) and a brief analysis of propaganda.
pick what you like and spin it.
