I want to know the answer to the following question:
What historic era did the Fantastic Four initially inhabit?
All the background I'm provided with is that "Eschewing such comic-book tropes as secret identities and even costumes at first, having a monster as one of the heroes, and having its characters bicker and complain in what was later called a "superheroes in the real world" approach, the series represented a change that proved to be a great success.". Is that enough to answer the question?
Answer: no
