I have a couple of old postcards where the standard tourist shot of a town has been spiced up with an airplane or airship flying overhead.
This one was the cornerstone of my Esperanto collection. It features a zeppelin flying over Rüstringen in Oldenburg, Germany (now part of the city of Wilhelmshaven).


And here's an old-timey aeroplane flying over Pardubice in Bohemia, Austria-Hungary (now in the Czech Republic). The combination of the photo, the Esperanto inscription, and the extraordinary handwriting made this a must-buy.


Does anyone else here have similar postcards? (They don't need to be written in Esperanto!)
