Really? Downvoted? Did no one else find the sexism in that poster as noticeable as I did?

I fully agree that it is an artifact from a different time. It wasn't considered to be sexist at the time and it wasn't intended to be sexist, but from todays point of view, it's definititely sexist.
It's interesting how our minds work alike in the same wrong ways, because I had pretty much the same train of thought.
