Roberta and I found 3 phrases we thought were anachronisms. Commenter latenac did the research and none of them are, in fact, anachronistic for 1960. This isn’t the first time we’ve discovered this sort of thing.
Here’s an interesting question: Why did they sound as if they were?
I think it’s because people in the movies and TV of 1960 didn’t talk much like the real people of 1960; certainly not to the extent that realistic dialogue exists (or attempts to exist, depending upon the skill of the writer) today.
This is one of Weiner’s themes, of course, that the people in Mad Men aren’t people in movies; they’re people who watch people in movies. 1960, I am so over you.
