"Bob Powell" and "Carl Wessler" are two veteran artist/writers. The use of their names may mean one or both were involved in the story or it may be an inside joke by the author.
The Skywald reprint has minor art modifications to reflect the era (longer sideburns on the men, women wearing pants instead of dresses) and has been re-colored. In all other respects, the stories appear to be identical.
