Hey! That's the creature from the black lagoon, isn't it?!? Or a distant cousin perhaps?
The cover scene is actually taken from a story in this comic - in which a 1950's bathing beauty is abducted by the Creature and taken to its underwater world where she is made the reluctant Queen of the underwater creatures' civilization. Wow, not a bad deal - a lot of maidens get eaten by monsters but this gal gets to be a Queen!
