I have a set of the initial Tarzan stories by Edgar Rice Burroughs. Books are # 1-24. The books that are black are the Neal Adams covers. The white covers are, clearly, different and not Neal Adams. All the books are in respectable condition, no covers falling off or significant splitting to spinal column, however they have actually been around the block. Still a good set, completely legible and the Neal Adams covers are a little of a collectors thing.
