In the early 1970’s comic books decided to become “relevant” and felt the need to deal with more complex social and racial issues.
Here’s the cover of Lois Lane 106 (Nov. 1970). In search of a story, Lois decides that she needs to live as a black woman for 24 hours and with Superman’s help is able to achieve a transformation.
As expected she is treated poorly by some and better by others.. All in all a bizarre scenerio.
