The Paris Métro has always had lamps by the station entrances, which are often referred to by the people who refer to this sort of thing as totems. These have been in a variety of styles, becoming less ornate over the years. This example is from the second re-imagining in 1924, and replaced the Val d'Osne style in the 1930s.
This one says
The lampost you can see at the entrance to this station was designed by the architect Dervaux and first installed in 1924 at Sèvres-Babylone station.
The model spread rapidly. Very sober, it replaced the wrought iron Val d'Osne lamp or the Art Nouveau post created in 1900 by Hector Guimard. It could be set either on a simple post also designed by Dervaux or stone posts. More rarely, it could finish off a Guimard post.
The cut out letters of the abbreviation 'Métro' are typically Art Deco. Generally inscribed in white on a red background, the sign is surmounted by a white lamp lit at night.
