I'm not entirely sure, but her autograph changes varies of times. It looks a lot like this signature: http://tstr.nl/data/autograph/Mariah+Carey.jpg

I'm not entirely sure, but I would say it's real.

"Mariah" looks good but the "Carey" does look odd! and she usually puts Love Mariah so the ball is in your court.

I would say no
