The metro station I’m normally using, Brochant, in the 17th arrondissement, is being renovated at the moment. I have not been able to find out what it will look like in couple of weeks (months?), but what is clear is that the original decoration from 1912 now is visible. It was until recently hidden by advertising placarding.
You can now again see the original tiles, including the station name in origin, manufactured by Les Faïencerie de Gien, still a renowned faience manufacturer.The previous “decoration” which now will be renewed dates obviously from around 1961, according to different documents left on the walls. You can actually read some regulations dating from 1951, but also some from 1961. There is also an indication that nine stations are closed (often since WW 2): Six of them are today again in operation: Bel Air, Champ de Mars, Cluny, Rennes, Liège and Varennes.
There is publicity for visiting the Orly airport. The first real modern passenger terminal at Orly (Orly Sud) was inaugurated by General de Gaulle in February 1961 and it became soon a Sunday pleasure for Parisians to visit this modern wonder. In the beginning of the 60’s, Orly had more tourist visitors than the Tour Eiffel! 
Another curiosity is perhaps to read some advertised phone numbers like ANJou 3118. The letters ANJ corresponded to A=2, N=6, J=5, meaning that we have here a phone number with seven digits: 265 3118. Today our numbers are not any more in letters and consist of 10 digits, but you can still find the letters - together with the figures - on modern phones, as well fixed as mobile ones.
