Those photos are from Star Wars Celebration IV convention. Frank Kozik, Paul Frank Sunich, Marc Ecko and Urban Medium (among numerous others) gave Darth Vader's helmet a hipster makeover. As fans walk through the exhibit they can see the artist's own unique style featured on each helmet. Whether it's a Tiki-inspired design from Shag or a girlie 1940's style pinup from Marc Ecko - it's apparent each artist took time to pay special tribute to the headwear of the Sith.
