One more pre-Marvel Thor-themed story by Jack Kirby!
Ironically, published in Tales of the UnExpected #16 (1957), a DC Comic!
AFAIK, Jack Kirby penciled and inked this particular story.(Usually, he just penciled, since he was so freakin' FAST!)
The Thor in this tale is visually-similar to his villainous "Thor impostor" from The Sandman story in Adventure Comics #75
The Mjolnir, however, is a dead ringer for the Marvel Comics' Thor's...
If you want to see the Golden Age Thor, his adventures can be found in our brother blog, Hero & Heroine Histories™.
