Issue: Journey into Mystery # 111
Writer: Stan Lee
Artist: Jack Kirby
Publication Date: December 1964
This issue, we learn a little of Odin's past. It seems that he too was once in love with someone who was forbidden to him, just as Thor loves Jane Foster. For this reason, Odin decides to help Jane Foster stay alive. Of course, he then trusts Loki to help with that process. Fortunately, Odin's pals don't trust Loki any further than they can kick him down the rainbow bridge, so they do their best to prevent the trickster from causing any more harm.
Baldur plays a key role in this story, as it is he who manages to deliver the medicine to Thor that saves Jane Foster's life. Also, Mr. Hyde and Cobra have nothing. Zip.
In the backup story, Thor fights Sigurd, son of the Earth Sprites. Thor gives him the rock down.
Ladies and gentlemen, Stan Lee, master of comic irony.
