This has probably been my second favorite Atlas Era masterwork next to the Black Knight/Yellow Claw volume. I'm somewhat at a loss to adequately explain why this is the case. The stories in this issue are generally no better and no worse than the ones in other Atlas Era masterworks, that is to say, juvenile at best and wretched at worst.
I think the thing that won me over was consistency - both in script and art. The art was by Werner Roth and he is admirably suited for stories featuring attractive women. This masterwork is very easy on the male eyes.
But beyond the "good girl" art there is something that just works with Don Rico's scripts. At face value it's childish and unrealistic. The jungle consists of animals (both real and imaginary, plenty of the latter) which without exception seem to have human intelligence, moral values, and motivations. Rico seems to work this premise into one satisfying morality tale after another.
The book itself seems a little thin; only nine issues instead of the usual 10. But perhaps they needed this number so future volumes will work out right. I can't recommend this book to anyone other than comic book fans who know what they're getting into, but it's easy to see why these comic books came up when new Atlas masterworks were being proposed.
