Here are two vintage New York City Subway PSAs, courtesy of the Kino Library (the same folks who brought you this grimy ’80s East Village footage), as dug up by Bowery Boogie. One is from the ’40s; the other from the ’70s. Both are fantastic.

The ’70s spot in particular seems angled at tourists, advertising the opportunity to “mingle with the New Yorkers” and describing the subway’s “endless tide of humanity” as if that’s at all a pleasant thing.
