First off let me start with a few details.
1. Neil Gaiman wrote a book called Coraline
2. Henry Selik and the company Laika decided to animate a movie based on the book using stop motion
3. Promotions were arranged
Now one of the promotions was a collection of 50 boxes to be distributed around the world, each containing various items from the movie. I emailed Neil asking if any were available but after talking to Laika I was told they had all gone but I was to be sent one of "part two" of the promotion.
This is what arrived. No idea how many have been made but I have spotted a few around already.

Also my beautiful girlfriend decided to get hold of one of the Coraline keys for me which were nailed to a variety of places around the US.

Now I just have to wait for the movie to be released over here in the UK
