2. Darth Vader Mask
"Darth Vader? That wasn't a mask, that was a helmet!" one might argue. Probably you just did. It could be counter-argued that Darth Vader wore more than just a helmet, just as in the end, Boba Fett was more than just some giant sand-worm's appetizer. Darth's helmet/mask allowed him to be who he was, which was the mask, which was him. It all makes perfect subtext in a pretty standard George Lucas non-subtextual way. Nobody goes around comic-cons or standing outside movie theaters in line for re-releases looking like Anakin Skywalker revealed because, let's face it, that was ugly. Darth's mask brought terror into all those that gazed upon it with its soulless black eyes, it's black mouth-grill and its shades of black transposed with other shades of black to create the most iconic science fiction mask of all time. Plus, it made for a bitchin' piggy bank.
