It’s interesting that Amazing Stories fits the ladies on their covers with definite – if sometimes translucent – clothing, while Weird Tales found long hair – strategically placed – and careful posing were usually adequate to protect public morality.
Does this reflect the publishers’ different policies, or was there a definite change in what was acceptable with WWII?
