J.K. Rowling signs statue

Or should it read "J.K. Rowling defaces statue"? The author of the Harry Potter books finished the final novel in the series at Balmoral Hotel in Scotland. Before leaving the hotel she wrote, in black marker, on a statue in the hotel: "JK Rowling finished writing Harry Potter And The Deathly Hallows in this room on 11 Jan 2007". I think it is pretty cool because I am a Harry Potter fan and a J. K. Rowling fan as well, so the idea of her happily scrawling a message on a statue after completing this amazing journey she has been on with the boy wizard appeals to me. I don't think it was anything malicious but I can't help wondering if they knew she was going to do this or did she just decide, on the spur of the moment, to write on a statue in a hotel.

Now, the hotel won't say anything against it, for sure, because of the publicity. Besides, I am sure that someone with way too much money would pay oodles for the statue if the Balmoral ever wants to sell it and they could probably get thousands of Harry Potter fans to pay top dollar just to step into the room, let alone stay there all night. Who would complain about that?

A spokeswoman for the hotel said "We have many different antique artefacts within the hotel". So did Rowling write on an antique artifact? That wouldn't be good. Why not scribble on something that's not an antique statue? Maybe the mini-bar or the room service menu. Maybe the desk in the room. Or, if she was going for something more dramatic, why not carve the words into the desk? Black marker on a marble statue just seems a little curious to me.
