This find seems a lot like a hypothetical discovery of the "oldest surviving Parisian passenger bus map, dated 1952 [1]." It wouldn't be the oldest bus map, nor even the oldest bus map of Paris, nor would it tell you much about the Parisian bus system that you couldn't find from other sources. [1] I'm aware there are likely older surviving maps, but I made this up to make a point.
