Beginning with Tarzan, the pulp era was full of jungle heroes. Jungle Jim is one of the unique ones. He was not a barely-literate loincloth-clad tree-dwelling wild man, but rather Jim Bradley, a great white hunter in the mold of heroes of earlier popular fiction such as H. Rider Haggard's Allan Quatermain and Lord John Roxton from Arthur Conan Doyle's The Lost World, who represented the colonial view of the so-called primitive regions of the globe. This gave him a distinctive difference from your run-of-the-mill jungle man, who often knew little about civilization and was equipped with not much more than a knife in most cases. Also, his stomping grounds were located in exotic southeastern Asia.
