Witcher, Hyperdimension Neptunia Artbook Questions

[tfughost]

I recently bought a Witcher 2 Hardcover Comic Book, Hyperdymension Neptunia Artbook and Asura's Wrath Artbook.

I was wondering if anyone knew where these initially came from. If they were a preorder bonus, in a Collector's Edition or just bought on the side.

The Witcher 2 Comic says it was meant for the UK market, and everything is in English.

I've been trying to look this up myself, but I haven't found anything. Any additional information would be appreciated.
