This cover (front and part of back shown above) was sent from St Wolfgang to Wien; 5 Aug 1938. Light brownish express label. Franked 54Rpf on front & 6Rpf on back; total 60Rpf. Letter rate 12Rpf + express fee 40Rpf + pneu fee 10Rpf makes 62Rpf. Perhaps the pneumatic component was deemed irrelevant, in which case itís 8Rpf overfranked.
