Paul Hodge is credited to Wild Boy on pencils and ink by Jerry Bails' Who's Who, and compared with signed work in various Marvel comics, this must be him, as the other possible, Frank Kramer credited by Vadebonceur to some other Wild Boy stories is quite different. The eyes here are placed far apart, and the ears are special and identical to signed Hodge art. Also the sideview of the face of the witch doctor compare favorable with Hodge work. His work has many similarities with Charles Raab, but Raab is not credited to Wild Boy.
Same art as the first story.
Irv Novick and Bernard Sachs are both credited to "Joe Barton" by Jerry Bails' Who's Who, and the faces with lightning eyebrows are like Novick's work. The inking by Sachs match his credited work in "Mystery in Space" #3.
