The book presents itself as a compendium of magic tricks illustrated by drawings of various Happy Haunts of the Haunted Mansion, and written by Phineas J. Pock.
Behind the scenes
This book was printed in 1970 and promoted the then-brand-new Haunted Mansion.
The illustrations (whose author is unknown) were closely based on various pieces of concept art for the ride, and are, in places, evidence of concepts that didn't make the final cut — for example, the Stretching Room skeleton appears to be a woman with a large feathered hat, instead of the Ghost Host). In the same spirit, the book refers to its narrator (whose role, and appearance in illustrations, make it clear that he is the Ghost Host) as "Phineas J. Pock", mirroring a scrapped tombstone for Phineas Pock - Lord and Master that would have confirmed this as the Ghost Host's name.
