Strange that they felt the need to replace it with anything. Especially a photo of Brooke Shields in a bikini.
But I suppose there are those who get positively transported by such an image....
I wonder whether the folks (as in, Tate museum curators and directors, etc.) who thought it was perfectly legit to display the original would have thought the same if it was their own little daughter in the photo, and not Ms. Shields. I bet they wouldn't.
