An interesting discovery on how Wonder Woman was perceived in WWII comes through the Google News Archive.
Dated October 22, 1942, page 4, from the Ludington Daily News, entitled "Aren’t They All?":
No doubt it had to come. With women being called in the armed forces, recruited in industry and enlisted in nearly all other efforts which contribute to the war effort, it probably was inevitable that there should be a female counterpart to that greatest of all fictional males, Superman. It was only right that Superman not be left alone to hog the act in typical male fashion. So now we have Wonder Woman, as strong and courageous as any man and maybe more so.
After recalling the Powerful Katrinka of the old Toonerville Folks comic strip:
But Wonder Woman is not Katrinka. She is Katrinka with brains, possessing not merely brute strength, but a subtle kind of strength that is both mental and physical. It is a type of all-pervading power knowing no limits, and that isn’t as fictional as it sounds, for how expanding is the role of women in the rapidly shifting world around us.
The author only briefly discusses the Wonder Woman magazine which they haven’t seen or read. Apparently the publishers sent around the results of a questionnaire on the “wonder women of history”. The author likes most of the choices, but wishes earlier historical women were included as well. Then they concluded — “Wonder women. Aren’t they all?”
