Shepard Fairey.

Obey.

In 1989, as a student at Rhode Island School of Design (RISD), Fairy created a stencil of the famous wrestler Andre the Giant and added the caption “Andre the Giant has a Posse.” He made stickers that he posted all over Providence. They caused a commotion. After a while, he simplified the image by cropping it. He changed the caption to “Obey Giant,” and then to just “Obey.” He says that is the message of all advertising.

“If my manifesto could be condensed to two sentences, they would be: Empower yourself and question everything,” he told an interviewer. “People are paralyzed by fears of failure and they think their efforts won’t make a difference.”
