The covers are gorgeous, it makes a lot more sense why Dita Von Teese said she was inspired by her father's old Playboys. There's a lot of feminine, coquettish charm in the girls from the 60s-70s.
About the shift in the early 90s, I know nothing about Playboy's history but wasn't Hef on his last marriage when he was trying to "reform his ways" and his daughter Christie started to shore up the business side of Playboy and assumed more responsibility for Playboy? I wonder if a shift in management/people somehow influenced that? (Feel free to correct me though.)
And I never knew you could make Dr. Pepper hot toddys (1st pg).
