"Bar car" on the NYC subway, 1962

It was a temporary stunt as part of a city-wide cleanup. The goal was to give a “first class experience” to commuters.

It looks like something has broken in the USA in the '70s. It only went downward from there…
It didn’t start out from a good place either. US in the 70s was still homophobic, racist, and bombed the shit out of middle east. Reminds you of anything?
