Obey is a seemingly antiauthoritarian clothing brand started by guerrilla street artist Shepard Fairey as an inside joke and marketing campaign by which stickers featuring Andre the Giant were plastered all over public places by skateboarders.

The Obey clothing line is almost as successful as his phenomenal folk marketing skills. You can find several pieces for sale on eBay:
