A flacon montre by Guerlain can be seen on the dressing table Marianne Faithfull was sitting at. This portrait was taken on February 15th, 1974 by Hoare. The black and white makes impossible to see the colour of the front sticker, hence to know what cologne it was. My guess is that it was a classic – Shalimar.
The spray bottle with the geometric stopper is another Guerlain product – the perfumed deodorant version of Chant d’Arômes, a perfume created by Jean-Paul Guerlain in 1962.
