So here's Stan & John bringing Thor & Hela together on Earth, I think the first time we ever saw the Goddess Of Death looking like a mere mortal, albeit a kinda hot and vaguely russian one.
If I'm honest, Thor was never one of my main buys in the Bronze Age, mainly 'cos I struggled with all the thee's & thou's dialogue, feeling that it slowed Kirby's ( and Buscema's ) artwork down in much the same way stopping to read Zatanna's spells did, but there were individual runs I liked a lot, and this is one of them.
Mainly 'cos Hela was always a genuine threat, as opposed to say, The Wrecker.
And as well as her, you also get Balder The Bland still refusing to get off with Karnilla ( something he seemed to drag out for the whole of the Bronze Age ), and Odin sending Volstagg, of all the options to hand, down to Midgard to save the day. Valhalla, I am coming.
