I’m looking for an old movie (maybe black and white) or an episode of a TV Series. The plot is a sort of female version of Dorian Gray, but it is not the movie of 1983 (The Sins of Dorian Gray).
A woman is always young, a picture (photo) ages to her place.
At the end a friend burns her picture and she is reduced to ashes (while she is descending a staircase).
