Official The Hobbit 3D Glasses

Italian website HobbitFilm has posted the below images of official 3D glasses for The Hobbit: An Unexpected Journey. Much like with a simliar promotion for the last Harry Potter film, the 3D glasses will be available at select theatres for an extra cost when the film premieres on December 14th, 2012. The unusually look is so in part so the "uniquely designed folding arm frame and hammer forged steel look." Not sure what that means, they look like a key to me when folded up, something that fits since a key is needed to enter the Lonely Mountains in the films.
