“The Hammer and the Holocaust”
Stan (The Man) Lee and Jack (King) Kirby have created yon epic enchantment just for thee! Embellished by: Vince Colletta/ Lettered by: Sam Rosen
This is the second issue of Thor titled “The Hammer and the Holocaust”. It does not appear to be a reference to anything. Presumably Stan just liked the phrase.
Thor fights the Mangog with all the power he has, including the power of the storm. He pours so much lightning into the area that the ground turns molten. He batters the beast with blinding rain and pounding wind, but he only slows his foe, he cannot stop it.
Meanwhile the Colonizers have sent the Recorder to Asgard to bear witness to these events, which may be the end of all things.
