Here's one from the later sets of Darkover images that were published as frontispieces in the long-gone Gregg Press collector's item series. This one is for "Star of Danger," one of author Bradley's earliest Darkover books. In the story, which was aimed at younger readers, the son of an Earth civil servant sent to Darkover makes friends with a local boy. The illustration depicts some of the different characters who appear in the tale.
