Long time, first time. Since you and your readers have such success in tracking down traumas, I was hoping that you could help me with mine. It must have been a PSA from the mid-seventies, and was probably exclusive to the New York City area, given the content. A grave-sounding narrator described the action as it happened – a man with a rocking 70's-'stache is reading a newspaper on a subway platform. He drops it to the tracks, and leaps down to retrieve it. You know were this is going – the train comes, and the PSA ends with the sound of a train breaking, and a series of still images of the guy holding his hand in front of his face, eyes wide, the train's headlights brighter and brighter on him, each still closer and closer to his face.
My father took the train to work and read the paper every day. This so traumatized me that I remember standing in our kitchen pleading with him to leave his newspaper if he ever dropped it. I've been unsuccessful in finding it online – searching for "70's NY subway PSA" yields only the "New York – let's clean up New York" litter PSA. I'd be most grateful if your readers could help me pick off this almost-40-year-old scab!
