Here's some pictures from XiXiDu (?) of all the original German covers, though many of them are not all that original. One there is from Arthur C Clarke's 2010 (spot the monolith) and another is from a John Meaney book. Perhaps someone can tell me what the others are from? Not that I'm complaining, Lubbe has bough books of mine before I've even written them and is always the first foreign publisher to publish new ones!
