London Underground Map

A puzzle of the London Underground as in the 1990's. However, the whimsies all have an American theme, eg Statue of Liberty, Eagle and the letters 'USA'. This may have been a mistake however this example was purchased from a previous owner in the USA so it is just possible that a batch of these puzzles was ordered by an outlet in America and Wentworth selected the whimsies accordingly?

Thanks to Steffie Leib for the photos and information on this example.
