| @zoopy: It's rather difficult to define Germany for 1800 and 1849 as, in more or less its current form, it was only founded in 1871. Before that there were many different states. In 1871 however, Austria was not part of the club, so Vienna disappears, peeks up again after 1938 and leaves again in 1945.
Got all but two - Prague ist bad enough, but how I could miss Cologne is beyond me... |
