The two posters available online for Le meilleur de la vie (1985) break IMDb's guidelines
The current poster (https://www.imdb.com/title/tt0089577/mediaviewer/rm2890088704/) for Le meilleur de la vie (https://www.imdb.com/title/tt0089577/mediaviewer/rm2890088704/) is incorrect, it was modified. The white rectangle isn't part of any official posters for the film.
The problem is the only official poster I could find contains sexually suggestive or prurient images containing children since Sandra Bonnaire was 17 when the film was shot.
PS: To respect the forum's policy I didn't link the official poster.
There are two posters for one film, but both break IMDb's guidelines.
The altered one breaks

The official one breaks

I would suggest removing the current poster without adding a new one, therefore, the film wouldn't have a poster at all. But, there is also a rule prohibiting it.
Submitting a request to delete the existing 'primary' poster, before the new one is live will result in your contribution being discarded.
