The image you can see below is the illustration that Victoria Francés made for the cover of a german book. The saga is called "Aullidos" ("Howls", well I supose in german the tittle must be "Heulen"), but I can't find any information even of the book. So, I don't know if there is a bookmark of this book or books, but it would be so nice :)
If you have any information about the book or the bookmark, please, PLEASE!! leave a comment or contact me!
