This was a newspaper comic strip that first appeared in the 1930s. Later it became a
radio program, a series of movies, and eventually a TV show that lasted only a single season. The movies and the TV show both starred
Johnny Weissmuller (who also played Tarzan in several moves during that same period of time). Jungle Jim was a hunter, not a "
noble savage" like Tarzan.
I remember visiting my
cousins in Los Angeles in 1956 and watching Jungle Jim on television.
