Okay, I have purchased a poster from this seller.
But, I don't know if its original or reprint.
It is hard to find and this seller is the only one that I know that has the poster.
Its on glossy paper, but the poster measures 27x39.
How else can I tell for sure if its original or not, or if it was one that was sold at one of those conventions?
I don't really want to post the title as many won't even know of the movie.
