I only own this book as part of an overall geekdom for Clive Barker, and don't really imagine it would be in my library of art books otherwise. While his artwork is interesting as a part of the greater mythology of Barker's work, I don't really find it particularly compelling.
The book itself does an adequate job presenting the art itself, but fails as a legitimate art book in mislabelling pieces which have titles clearly written on them, not noting sizes or media for any of the art, and completely ignoring any data for the brief colour section at the start. Fred Burke's running commentary is interesting, though it's largely comprised of Barker interview quotes. Unfortunately, Burke's text often refers to art not found anywhere near the reference (and even nowhere in the book at least once).
This was, however, a high-end publication from a company more heavily devoted to comics (and trading cards) all through the 90s. With that considered, not a bad book altogether, but still better for fans than for art buffs.
