1862 Hamburg, Thurn and Taxis Prephilately, German States, Germany, Folded Letter from Hamburg to Borgosesia (Italy), Hambrug Thurn and Taxis Postmark

1862 Folded letter from Hamburg to Borgosesia, Italy. The circular postmark on the right (dated June 3, 1862) belongs to the Thurn and Taxis Post Office in Hamburg.Although Hamburg had its own city post, the Thurn and Taxis dynasty operated its own office there to manage mail heading toward Southern Europe, including Italy, France, and Switzerland. The red framed "P.D." stands for "Payé jusqu'à Destination" (Paid to Destination). This indicated that the sender had paid the full international postage upfront.

It has a ransit postmark from Frankfurt (June 4th) on reverse. The other postmark "AMBS. BUREAU" confirms the letter was processed in a mobile railway post office while heading south, likely passing through Switzerland or the Austrian Empire. Arrival in Italy (Novara & Borgosesia) on June 7th.

For 1862, a four-day transit from Hamburg to a smaller Italian town like Borgosesia demonstrates the high efficiency of the expanding European railway network and international postal treaties.
