Well, that's the one I bought.
I'm quite happy with it, but I'd rather have the normal Mosaic jewel cases. In this "Spiegel Edition" which, by the way, has been available from the Spiegel Shop online for quite some time now (and has been advertised in their magazine since last year), the CDs are in cardboard sleeves which are inserted into slits in the inside front and back covers. I'll probably remove the CDs and put them into jewel cases. It's just a hassle with the covers and tracklists.
The booklet (as tall as the box) has the (translated) German version only notes from the Mosaic set (complete, as far as I can tell). There is a single black info sheet affixed to the backcover of the package by a piece of round tape, giving some general info and listing Mosaic as the copyright holder (distributed by "Warner Strategic Marketing International". Finally it states "Made in Germany by Warner Music Manufacturing Europe"
