I'm not entirely sure if there are explicit novel writers in 'Mad Men'. The series is mainly about the advertising business in the 1960s. But considering the creative environment depicted, it wouldn't be far - fetched to assume that there could be someone involved with novel writing on the periphery. Maybe some of the more artistic characters could have dabbled in it.
Mad Men is not based on a true story. It's a creation of the show's writers and producers, drawing inspiration from various elements of the era it portrays but not directly from real-life events or individuals. The show's focus is on fictional characters and their fictional storylines within the advertising world of the 1960s.
Mad Men was not based on actual events. It was a fictional concept developed to explore various themes and characters within a certain period and industry setting.
The 'a mad tea party short story' presents a rather curious scenario. At the tea party, the Hatter is constantly spouting off about various things in a rather mad way. The March Hare is equally as strange, and they both seem to be in a world of their own. The Dormouse, which is often dozing off, is also part of this strange gathering. They discuss things like the concept of time, but in a way that is completely different from how we understand it in the real world. Their behavior is erratic, and the whole tea party is a display of madness and illogicality.
I'm not sure there are specifically defined 'erotic stories' in a mainstream sense for 'Mad Men'. The show mainly focused on the advertising world in the 1960s. It did have storylines about relationships and affairs, but not in a purely 'erotic story' way. It was more about the complex relationships between the characters, like Don Draper's many affairs which were more about his character's flaws and the social context of the time.
Well, in 'Mad Men' fanfiction, a prevalent theme is the reimagining of the characters' fates. For instance, what if Peggy Olson had left Sterling Cooper earlier? This idea of 'what if' scenarios is very common. Also, the power dynamics within the advertising agency is often explored. How the different characters jockey for position, like Pete Campbell trying to climb the corporate ladder in new and different ways. And of course, the theme of the changing social norms of the time period. Fanfiction might show how the characters adapt or resist these changes more than what was shown in the original series.
