I'm sorry about the brazenly misleading title of this post. It's just that the last couple of months have been full of jungle and space pulp comics on various blogs. I kept thinking I'd wait until they started to dwindle and then do a huge post linking to everything, but they're still going strong and collecting all the links is a single post would be very unwieldy. So I'll break these into several posts instead.
The usual warnings about racism in Golden Age jungle comics apply.
Cave Girl and the Mau Mau Killers

Alani the South Seas Girl and the Bloody Axe
A jungle girl and pirates! [Pappy's Golden Age Comics Blogzine]
Tarzan: Lord of the Jungle
Roy Thomas and John Buscema's version of the origin story. [Diversions of the Groovy Kind]
If space girls are more your interest, Sleestak posted a couple of more Futura stories.
