The Coraline Press kit came with a CD containing some production photos, a Low Res Trailer and Production Notes. The CD was attached to a cardboard lithograph. It is now been added to my Coraline collection. Mary-Frances and I attended the Emerald City Comic-Con and got to meet Chris Turnham, one of the production illustrators for Coraline to sign it.
I also acquired one of the production Keys that where spread around town to help promote the movie and website. I wasn't fortunate enough to find one, but eBay is a good place to find them now. The second key, is my first key of 50, from the Mystery Box's. I believe this key matches Mystery Box No. 29
