The cover you see to the right was the image that was on the first copy of this book I bought in the early 1970s. I still have that book on my shelf (along with every other Edgard Rice Burroughs novel). I picked up an audio book of this recently, and I am pleasantly surprised at how much fun I'm having with it! Edgar Rice Burroughs' books were probably more important to me than those of any other author in making me passionate about science fiction adventure novels! The old-fashioned writing style is very different from today's novels, but that's what makes it so much fun. I just might have to revisit the entire John Carter Mars series!
