The retro-style opening credits of the film (designed by Juan Gatti) contain, quite surprisingly, a real advert of a real make-up item.
It’s the marbled lipstick Glissando, launched in 1964 by the American brand Du Barry.
Available in six shades (“from light-struck pinks to muted ambers to rich reds”), it was housed in an elegant silver and gold metal case.
It’s true the brand started its decline in the 1970s and eventually died , but I still wonder what happened here. Did the title designer get away with reproducing an advert of a defunct brand? Or did they just paid what was due to whatever multinational company owned the Du Barry name in the 1980s?
 This is not entirely accurate: the brand was relaunched in 2002. But I guess that was the end of it.
