I was first alerted to this 'poster' for The Hobbit: The Desolation Of Smaug by TheOneRing, who pointed out that it we haven't really seen many posters for the new Hobbit film yet. And that here was a new one.
But is it? I wonder if TheOneRing were so sure, as they refer to it a couple of times as "poster artwork".
I did a bit of digging and it would seem that this is actually an image for a Jigsaw.
Still, it is rather a nice image. Maybe it'll be used for a poster too at some point.
