This one was a small white plaque screwed into a brick wall in a non-descript back street, but what particularly stood out was the date of the law. This was not the standard 1881 decree, but rather one that dated from 1943 and France's infamous Vichy regime.
As the scrawled message on the plaque says, this was indeed a 'loi Pétainiste' (or rather a 'loi Laval'), but what exactly is being forbidden here?
The message writer here has spotted the date, and looked to make comparisons between France's collaborist state during the Second World War and today's perceived authoritarian rulers, but in reality the law mentioned is rather banal. However, it is also one that had a big effect on the way French cities looked.
Look back at old photos of Paris and you will see advertising painted onto all visible wall surfaces. Some of these traces remain as so called 'ghost signs', but this law is in fact the edict that signed their death warrant. It was the first law in the country that seeked to protect the esthetics of the city from rampant advertising, limiting the publicity to a restrictive maximum size and height.
The first question is very difficult to answer. It is unlikey that the law had anything to do with restricting the actions of the resistance, and is probably more a reflection of the lack of important decisions the puppet state had to make.
