I'm not sure about Alien Vault, as I haven't read it, but I'd say yes. I'm certain all of the images have, at some stage, made it into the DVD, blu-ray, and endless other "making-of" publications, but it also has Giger's commentary on the project from his first discussions with O'Bannon, right up until the finished picture. If you're interested in Giger's involvement in the production it's a fairly invaluable resource just for the insight he gives into what went on.
