In London, there is a woman who goes on the subway every day and sits on the dock just to listen to an advertisement that her husband recorded in 1950.
Margaret McCollum, after the death of Oswald Lawrence, sits on the bench waiting to hear this recording, which has become one of the most famous recordings in London: Pay attention to the distance between the train and the platform.
In 2003, Oswald died, leaving a huge void in Margaret's heart. So Margaret found a way to feel his presence closer.
When this audio was replaced by another electronic recording, Margaret ordered this cassette tape from the carrier to continue listening to her husband's voice at home.
After the company learned of the touching story, it decided to re-advertise at the only station close to the house where the woman lives, specifically at Embankment station on the Northern Line, where all passengers today can listen to the voice of Oswald Lawrence and think that eternal love really exists.
