SWITZERLAND - LANDSCHAFTSBILDER
Field post cancellations always add extra spice to a collection. This cover here bears a cancellation of "Verpfl. Abt. 4 Feldpost" on the 10c Landschaftsbilder of 1939. The sender is Hans Scholer, who was part of the medical staff there. I had a quick look on Google to see whether the names of both sender and recipient would yield anything and apparently there is a medical Hans Schöler but the dates don't seem to match. The dates of a certain Max Lauber (again connections in medical field) would match however, so who knows what the contents of this cover would have been like! Maybe just friends, or maybe being in search of medical advice? Intriguing!
