This handcrafted Poison Apple spellbook is by Craft Menagerie in California. The book is meant to be displayed open as a decoration, so the rest of the inside of the book is just random content. The spell book is made with paper, lace, and fabric.
Check out this really cool Haunted Mansion Halloween spellbook prop! Note that Madame Leota's hair glows in the dark - so cool! The book is a decoration and does not close. It's by Witch on Wheels in Connecticut.
Lastly, here's Pier 1's hand-carved resin Halloween spellbook. Love the skeletal hands holding it open!
