The series was created by Walter Gibson, who was also the writer of the long-running pulp magazine, The Shadow, writing as Maxwell Grant. And here I thought the stories of the Shadow were a stretch for credibility!
This story, from Space Western #41 (1952), by Walter Gibson and Stan Campbell, is full of the craziness for which Space Western is known. Intelligent cacti from Venus come to earth to get an atom bomb, which Spurs and his gang are supposed to guard. You have a notion of how such a story will go when it is based on such a premise.
