This issue is a variant of Wonder Woman (DC, 1942 series) #261.
Barcode appears on cover but has a line through it rendering it unscannable.
In part 1 of this story, Martin Markham's hair was black; in part 2, it was blond; and here, in part 3, it is brown. At the end of the story, the entire world had forgotten the events of the past few days -- except for Wonder Woman, who is still upset that the public could so quickly turn against her.
Letters from Patty Gadicke, N. Levine, and Jeff Turner.
