J.K. Rowling's Collector's Edition of The Tales of Beetle the Bard from the Harry Potter series.
The giant book is merely the case for the smaller story book. Every now and then, I think I smell a hint of musty on it but then I don't. I have no idea if the case presentation is messing with me because the inside smells like a new book.
This has been used as part of a collection so the story book has never been handled or read.
