Trying to get my eyes on all valuable iconographic sources on Leiber's duo I can manage to find (better scans, rarities, link suggestions and any such material more than welcome).
Two oniric covers by master illustrator
Karel Thole (for the italian edition by Editrice Nord)


A complete series of "covers" by
Andreas Martens (the images are linked from
Dossier Andreas , a very rich site on this great german artist, father of Rork, Capricorne and
Cromwell Stone





Covers by
Mike "seven wonders"
Mignola, realized (along with some interior art I couldn't get my hands on yet...) for the
White Wolf edition
