In the 1930s and the very early 1940s, before the Second World War, Cliff Crosby traveled the world, and had some very unusual adventures. In South America, he fought a giant octopus, then wore its corpse on his head, to frighten a gang of slave traders. In the Arctic Circle, he fought a cobra, and a polar bear, and met a roving tribe of African pioneers.
