On these two titles from Gold Key—tie-ins to science fiction TV shows produced by Irwin Allen—the writer credits are as straightforward as on Girl from UNCLE: one writer on each.
Art on both titles came from Tom Gill. I can't tell how much was contributed by John Verpoorten, who's known to have assisted Gill on Time Tunnel; Ted Galindo pencilled for Gill on Land of the Giants. The Time Tunnel covers were paintings by George Wilson; Giants used photo covers.
