Help With An Architectural Question About Vintage Paris, France

[CampLogan1917]

This is a question that has been stumping my networks of photographers and architects, literally, around the world. It finally ocurred to me that houstonarchitecture.com has a forum and a very knowledgeable readship that has always answered every question I have ever posed. Here it is in a nutshell, "This photo was taken in 1914 at 22 rue Saint-Sauveur in the 2nd Arrondissement in Paris, France. This structure no longer exists but it was part of what was known as "the old Paris". What I would like to ask someone, anyone to do is to look at this photo and notice the doorway that is to the left of center in the photo. There is an irregular shaped passageway and the doorway is right next to and to the left of this passageway. If you look above the doorway you will see a rectangular looking piece of either wood or metal that looks attached on both sides about one-third of the way down on either side of the doorway. Then it looks like it is hanging from the top down at approximately a 45 degree angle that's held by what looks like metal or some such material holding it at that angle. I hope I have explain this well enough for you to know what I am talking about. Does anyone out there know what this thing is that is hanging and/or what purpose it serves. Sometimes these old photos and/images show us something that is either archaic or so old that it is no longer used. Then it becomes what is it? Thanks."

Architectural firms never again can simply depend on the view of potential customers of their brilliance to produce business. Write my paper for money they want to separate themselves from their rivals and win new business by advertising their administrations and advantages emerging out of a business association with them.
