In my last posting, I presented examples of mixed (two-country) frankings that resulted when international reply cards were uprated upon being returned to the country of origin. Mixed frankings also occur when mail to a country enjoying a special treaty rate is forwarded to a non-treaty rate country. The example shown here illustrates this type of mixed franking.
On October 1, 1902, a special five-centime treaty rate for postcards sent from Luxembourg to Germany took effect, while the ten-centime UPU rate remained in effect for postcards sent to France. This privately printed commercial postcard was posted from Wecker, Luxembourg, on November 5, 1903, properly franked with a five-centime Adolphe definitive. However, upon arrival at Inglange [post Diesdorf] in the then-German Lorraine, it was forwarded to Bellac in the Haute Vienna Department of France. Since the rate from Luxembourg to France was 10 centimes, the deficiency was made up with a five-pfennig Germania definitive. The backstamp shows that the card was received on November 8, 1903 in Bellac, Haute Vienne, France. Forwarding within the UPU was free only if the initial franking satisfied the UPU rate, as this card nicely illustrates.
