According to a transcriber's note at the end of the text, this ebook was produced from the Analog, September 1962 publication. It includes reproductions of the original artwork by John Schoenherr. It gives both Harness and Thomas as authors; however, other, external evidence states that only Thomas was responsible for this story.
