I was hanging up my new HP Lego poster when I noticed a weird thing about it that didn't match up with the cover of the game. At first I thought I'd done something to the poster, but when I Google'd other images of the poster, they had this same weird thing on them.
In case you can't see it, X-TREME CLOSE-UP!!1!:
See that weird triangle thing above Hermione's wand? What is that?! I mean, there are other little differences between the poster and the game box, but nothing that can't be explained...except that weird triangle thing!
It doesn't really bother me, it's still a cool poster for an AWESOME game, and it works well to tie in the Harry Potter side of my living room with the computer games side.
