Harry Potter fans and collectors now have the chance to win one of ten exclusive hardcover copies of the new book, Harry Potter – The Unofficial Guide to the Collectibles of Our Favorite Wizard, months before it reaches retailers.

The new book features over 300 objects gathered from private and public collections. It is the first comprehensive guide of the art, books, and memorabilia that have been created over the past 20 years of Pottermania. At this point, first edition copies of J.K. Rowling’s first book in the series are now valued at nearly $50,000 and special items created for collectors are consistently rising in value.

In the beautifully illustrated tome, author Eric Bradley (Mantiques: A Manly Guide to Cool Stuff) introduces readers to the broad scope of Harry Potter collectibles and explores the fandom surrounding love of the boy wizard. This guide covers everything from the incredible sale of the chair Rowling used to write the series, which sold for an astounding $394,000, to an elaborate Potter-themed wedding, series tattoos, and more.
