Here is an example of the illustrated River Song diary that I purchased from a UK artist, as well as the blank 11th Dr diary and the Melody Malone dime novel that I also purchased from the same artist...

That's disappointing that the Experience is using replicas now. I don't care if it's nice, screen accurate, whatever, it's not from the show and shouldn't be there. It's kind of like having a forged painting in a museum, isn't it?
I believe some of the Sonics on show may be replicas.
(Perhaps the original was being used for filming?)
The Smith sonic, or do you mean Tennant? If Tennant, why would they be using it for filming? And if Smith, there are no replicas yet, anything made by Robatto counts as the real thing.
