An unnecessarily Serpent Crown story ends with Namor burying the headgear far beneath the sea.
It’s fascinating how much Roy Thomas’ writing improves when he’s working with a legendary artist. It happened here when he worked with John Buscema (and when he worked with Buscema on Avengers) and again in X-Men when he worked with Neal Adams. At this time, Thomas was both an editor and a writer, so it’s possible he was leaning heavy on artists to lay out a much better story than he himself could produce.
I’m not saying Marie Severin isn’t a good artist–she is. But (a) she’s not well-matched to undersea nobility and (b) she’s not John Buscema.
