In the film, OBEY is one of the subliminal one-word commands sent to the aliens through outdoor media.
In this piece, graffiti use of imagery, and moving away from just use of letters, steps toward being contemporary street art. That's significant with because as some of you may know, the film inspired Shepard Fairey’s OBEY and OBEY GIANT series.
Fairey has often talked about seeing the film after picking up a copy for $1 in 1993. “The film… has a rather profound concept, which is that people don’t realize they’re being manipulated because they’re so caught up in consumption and the rat race, the drag of day-to-day life, they don’t realize they’re being controlled,” Fairey said in the clip below.
That may be a lot to read in this mural, and it’s very possible the artists just liked the movie's way of warning how media is manipulating the masses, and the cool-looking zombie creature.
