Just yesterday I toured an old abandoned hotel that had a 4 x 8 wall map dating from 1949.
It was wild to see countries (or colonies?) such as French West Africa and Belgian Congo, as well as British Mandate colonies. Hawaii at the time was an American Territory.
The map even had a color-coded key to the "Colonial Powers" which included Britain, France, Portugal, Belgium, Spain and the United States.
Not sure that this relates to the OP, but it was like stepping back in time.
