I've read from multiple sources that French Algeria was considered an integral part of France during the run-up to WWII. The Pieds Noirs were ultimately a double-digit percentage of the population, and to pluck from Wikipedia's article on French Algeria, "Three civil territories — Alger, Oran, and Constantine — were organized as Departments of France (local administrative units) under a civilian government. This made them a part of France proper as opposed to a colony."

But it seems like there are few if any maps of France from the time period (1848-1962) that show "France" in its administrative entirety, together with the departments of Algeria, in one page. E.g., with the departments of Algeria as an inset like one would see Corsica (or today, French Guinea) as integral parts of the territory. This seems strange especially given the tendency of maps to be used as "legitimizing" propaganda (e.g., "Portugal não é um país pequeno"). What factors (historical, cultural, or political) would contribute to this apparent lack of what seems like a natural kind of map?
