Pages missing and lousy scans. Still better than nothing.

[Captain Audio]

I like that cover. Good if slightly stiff action pose and some truly gnarly birds.
Too many older superhero covers just show the subject posed as if competing in a Mr Universe contest, or sailing through the sky looking noble.

Some, but not all, of the panels of the first story remind me of Buscema's Conan illustrated stories.
The artwork seems like it was done by two different artists. Some panels are nicely detailed and the figures very well thought out with the illusion of motion while in others the drawings is stiff and simplistic.
Somehow it makes me think the story had been done as a straight western adventure that later on was adapted to fit this super hero.
