Firstly please excuse the poor quality of the photos!
I tried to get a couple of keyrings, but they could only let me have one.
The key ring is two metal dog tag style pieces, signed by SK on the backs of both:
Burgundy on the other side with "Stephen King" written on one and "Duma Key - Waterstones" written on the other:
They come in a small packet with a card that reads, "One of 5000 limited edition keyrings to celebrate publication of (picture of the book) produced exclusively for Waterstone's."
If you would like to be entered in the draw, post in this thread. I will pick a winner out of a hat on the 9th February - so you have 2 weeks to enter.
I'll post the winner in here and also pm you for your address. Good luck
