The best place to see Anke's art (besides her exhibitions of course) is her website. Of course better still is at home (I have a picture of Gandalf in my study). But not wishing to rival any of that, I have assembled all book covers Anke did for Walking Tree Publishers onto a single page. You can enlarge them by clicking.
