In the early 1950s, the legendary design group Pushpin Studio was called the "origin of pop art." Its founder, Seymour Chwast, who turned 90 years old, has reproduced over 200 archives with the latest digital technology, centering on his new work "POSTERMAN". Using on-demand printing, T-shirts and canvas posters are reproduced as media under the two themes of "wearing" and "decorating". The "pushpin phenomenon" that sparked the golden age of New York design. About half a century later, that legendary "push pin style" is revived in modern times.
