This comic is a winner! It shows how fine Dell comics could be: solid, well-written stories and good (in this case, excellent) artwork.
"The Earth Trembles" does have some stereotypes, mostly in the dialogue. The refreshing thing is that the Native Americans are depicted in the context of their own world, not as elements of the White Man's history. Decent story, good action. My only gripe is the excess of exclamations like "Wagh!" and "Hohee!"
I liked "Fangs of Fury" even more because of its unique take on prehistoric men. And I say "men" advisedly because Red Wing's tribe doesn't seem to have any women in it.
Now the art. Fabulous! It's amazing how much John Buscema matured in the five years since Indian Chief #13. Though there's still plenty to like in "White Eagle and the Hostage," Buscema's staging and posing were often awkward and his anatomy was just a little bit off. In this issue, though, he's in his prime. Assured, vibrant figures; crisp inking, strong posing. In fact, the main difference between this and his later Marvel classics is that Buscema stages everything at eye-level rather than changing camera angles. My single quibble: the men's faces tend to look alike (though varied costuming ensures we always know who's who).
Thanks, Mark, for recommending this read.
