The 1986 German edition of A Voyage to Arcturus featured 10 interior illustrations by Johan Peterka. They seem to have been created by placing cut-out line drawings on some sort of wash background. I’ve identified them below by page number, and the chapter in which they appear, but some of the illustrations are obviously of characters other than those named in the chapter titles — the “Haunte” chapter’s illustration, for instance, I’d guess is of Sullenbode.
