Believe what you will, it's all fine. My experience tells me that it's the real deal, and it's enough for me personally. Everybody is entitled to his/her opinion. Unfortunately, I have never been in the business of examining posters with a loupe, I only follow my instincts, so there is nothing I can prove one way or another. I spent $1,500 on mine, I am not an expert in posters, I don't even know what that means, but I've been collecting for some time and I know enough to be happy with this poster.
Sorry I couldn't be more specific, it's not my thing.
