“Sorry you haven’t seen very much of my artwork. I’ve been really busy doing the cover and all the interior illustrations for Harlan Ellison’s Last Dangerous Visions. I’m almost done. Sorry for the delay.” — Fox
Having recently read this story, the cover kinda-sorta looks like something that happened in it, but only in a very vague, kinda-sorta way.
