Random Cover of the Day: Mystery In Space #31

The GCD is down right now, so I can't check the artist, but it's a beautiful cover with terrific inking and dynamic perspective. This is a classic DC "puzzle" cover, where the goal was to get the kid to pick up the comic and find out how exactly the earth managed to get sliced in half like an orange.

Update: As pointed out by my old buddy Snard in the comments, the cover is by Gil Kane, one of the more prolific artists of the Silver Age.

Random Cover of the Day: House of Mystery #79

Comments: It's a "Great Scott!" cover; DC used that as its all-purpose expression of amazement. What can we deduce from this cover about the story inside? Note the title, "The Creature from Inner Space". Does this indicate that the creature came from inside the earth? Why is the protagonist driving a boat? Did he come across the creature inside a cave on an island?

If it's burning the water, it must be losing energy, right? What powers the creature?

Decent dramatic action by Jack Kirby according to the GCD, although the cover story was by Ruben Moreira.
