I just discovered who the artist was for the recent Polish Witch World books: Tomasz Maroński. I’ve created a section for his art under Cover Artists, and updated the associated book pages under The Witch World Series and Polish Editions.
I also found out that the artist for the Spanish edition of Witch World (Mundo de Brujas) did the cover for Die Braut des Tiermenschen (the German edition of Year of the Unicorn). His name is Enric Torres-Prat. I’ve added the information on the appropriate pages and created a section for him under Cover Artists.
And I discovered that Jeff Jones did the cover art for Angriff Der Schatten, the German edition of Warlock of the Witch World. That has also been added to the appropriate pages.
