Very hard to say. From modern it's probably the Riddell Stormtrooper helmet. I really love the Riddell helmets adn that one's just plain neat.
Vintage stuff would be Yakface. It's a cool figure, much better than the modern version. I thought I'd be paying a fortune for it but I managed to score it, in excellent condition for only $65 on ebay. I was the only guy that bid. Strange too because it was listed properly.
