That's one of the reasons this idol is so unusual. It was just released as the centerpiece of the "Cthulhu: The Ancient One Tribute Box", a book/gift set by author Steve Mockus. It's produced by Chronicle Books, a publishing house that specializes in niche tchotchkes. You've probably seen dozens of their products in the browsing racks at your local bookstore.
It's solid resin and is 4.5" tall. The inside packaging (which holds the book) also makes a nice display stand. I included a Bic lighter in some photos to show scale and a truer sense of the color than what you see on Amazon.I have to agree. It's an impressive sculpt, and a steal at $12, particularly if you can get free shipping through Amazon Prime.
The book included is nothing much to get excited about -- essentially a collection of trivia for someone who has never read Lovecraft and needs a primer on Cthulhu and its place in pop culture, etc. -- but the statue has some heft to it and is quite a nice sculpt for twelve bucks. (For the price, I'm tempted to buy a second and use them as bookends.)
