This listing is for a bookshelf stand for the Spiderwick Chronicles series. It is approximately 56 inches high and 8 inches wide. I have had this item sitting on my bookshelf for many years, but never had any idea of what it was supposed to do. However, I am guessing that it is intended to be used as shown in the second picture.
Please see my other listings for other books from this series as well as Spiderwick Chronicles collectibles.
