I have no words for this cover. Naturally, I had to have this book after seeing the cover. I don’t even care what this is about. Sci Fi from the old days usually has some of the most bizarre cover art. From the book’s description I am guessing that the phallic looking “thing” is called the wormway or rather a subway for this bizarre alien culture. I will leave it to you all to come up with your own jokes for this cover.
