Lucien Bourrache (Jean Gabin) is taking a bubble bath. Luxurious moment, since he’s surrounded by Guerlain products!

There are a bottle of talcum powder and two flacons montres by the tub. I wish I knew what colognes they contained, but some assumptions can be made. These bottles were introduced in the late 1930s, just one year before the film release, so they could contain Shalimar, Cachet Jaune or Mitsouko (all of them were launched in 1937).

Thanks to Despina Veneti for the id.
