Hand-made ‘Chief Cities Quartettes’ card game, c.1910 by an unknown artist. Each city from around the world has 4 cards with a hand drawn and painted image at the top and titles of the other three cards to complete the set handwritten at the bottom. Possibly inspired by a similar set (maybe Famous Cities or Counties) or perhaps photos in a book, the set must have taken some time to complete. In England this type of game was sometimes called "Happy Families", "Quartet" or "A Round Game" but "Quartette" could be from somewhere else in Europe.
The card for Edward VII is a clue: his correct date is 1901-1910. Queen Victoria was 1837-1901. This suggests that the author / artist may not have been acquainted with the current UK monarchy dates, and also that the cards would have been produced in or after 1910. There may be other clues.
