[#55]Very nice map, thanks for posting this!
In regard with the French Aeropostale air service to and from South America here is a July 1928 example from Buenos Aires to Thessaloniki, Greece. It is a very unusual destination for such an eraly (1928) date that I thought you might like it for your records.
Best Regards (and please forgive me writing in English!)
