1. Post modernism in graphic design is used loosely as a term to describe the climate of cultural change. It is difficult to describee because it is a concept that appears in a wide variety in areas of study, including art, architecture, music, film, literature, sociology, communication, fashion, and technology. It is also not clear when post modernism began, making it hard to locate historically,

2. Designers felt the need to reject some or all of International style because post modernists reject the modernist concept of the "master theory", a single concept or style (in this case, International style), that defines a field. Post modernists' stylistic conventions are plural and unstable, which goes against the dogmatic rules of International style.
