It is Like Goatse* for Star Trek

Interestingly enough, this is from a "Gen"^† Star Trek (The Original Series) fanzine from the late 1970s, and you can still find copies on eBay.

Had to be an amazing labor of love, because you would have to pay for a 4-color press to do that cover art, and that would have been some serious bank.

What the f%$# were they thinking with the artwork?

^*If you do not know what Goatse is, Do Not Google It!!!! That which is seen cannot be unseen.
^†Not containing sexual content, basically what you might find on broadcast TV.
