I picked up Mumbo Jumbo on clearance, a couple years back at a groovy store called The Alley.

Sort of like a funkier, less organized Home Goods.
For $5, I couldn't resist the great graphic illustrations inside Michael Roberts' collection, subtitled "The Creepy ABC." (Roberts is a talented artist who has created covers for The New Yorker.)
This is how I have it displayed, on the living room table:
