A
social movement started by
Shepard Fairey in the 1990's. The giant refers to
Andre the Giant, a late
professional wrestler who was massive (7'4" and 520 pounds). This movement is an experiment of
phenomenology and involves sticking large
posters and
stickers all over cities. The artwork features a two color picture of Andre the Giant and the the words
OBEY or GIANT or some combination thereof, or no lettering at all.
