A bit more detail on this Czechoslovak Airlines pinwheel from sometime around 1975. Looking at the inner circle, we see Prague connected to a number of European cities of both east and west, from Bucharest to Brussels to Barcelona. Tunis and Malta are looped together (as Emirates does today) and Algiers is shown as a southwestern outliner.
See the previous post for an overview, and details of the long-haul routes. The next post will also show some detail of the upper-right side of the cartogram.
