Just came about this Metro station in Paris. An ordinary station until 1994 when it was redesigned by belgium comic artist François Schuite. It‘s a bit hard to find a good web page, either they have a lot of cool pictures with french texts, or condensed dry information in english. So maybe try this: https://www.about-paris.com/art-et-metiers-metro.html
I would include more pictures, but as I haven’t been there, I didn’t wanted to grab to many pictures from other people off the web. This pictures above has a copyright, and for more you search on your own.
