Here's one from the old Peter Pan Records days:
To paraphrase Guy from Galaxy Quest; Did any these artists actually watch the show?
IIRC, and I could be wrong, but wasn't the artist on some of these books Neal Adams (one of DC's great artist -- Superman, Batman, Green Lantern/Green Arrow). I loved these when I was four because it looked so much like the show except for the secondary characters. It may have been a rights issue and the company may have had the rights only to Shatner, Nimoy and Kelly's likeness and had to fudge the rest. In one comic, they had a green M'Ress and a blond-human Arex.
