Got this facsimile from High Adventure. I'm always a sucker for Tarzan and his clones.

It isn't the worst thing I've read, but I have to put this in the bottom tier of the genre. Well below Tarzan, but also Ki-Gor, Kioga, Jann of the Jungle, and Bomba the Jungle Boy.

It's a story about finding a lost Ptolemeic civilization. It never explains exactly how these cities are able to last without any sort of trade routes, but that's meta reading. It's pretty lack luster. Ka-Zar mostly walks the streets of the city looking for a way out.

Considering that Ki-Gor is getting LOTS of exposure at Moonstone Comics with Return of the Originals, our own Airship 27 Productions Ki-Gor anthology (nearly completed) is going to undergo a mild name change to - JUNGLE TALES (featuring Ki-Gor) that way subsequent issues will not have to use him
and spotlight other classic pulp jungle heroes along the way.

That's great news! The more jungle stuff the better, I say!

While I'm thinking about it, is one of these companion features perhaps Kwa of the Jungle?
