Eugène Atget made a number of interesting sets of photos of aspects of Parisian life in the late 19th and early 20th centuries. The Bibliothèque Nationale de France has made a number of them available on the web. This is a detail from a photo of the Cabaret Alexandre, 100 boulevard de Clichy, printed between 1910 and 1912 from a negative taken in 1910. Great stuff! (I love the way the type echoes the form of the doors in this one.) See more here.
