Train service at the beginning of the 20th century was efficient and reliable. This card, carried on the rail line to Karthaus (near Trier), was received at the Trier, Germany, post office just a couple hours after it had been posted.
Marked “Eilboten” in blue crayon, surely the addressee received the card later that day—on the afternoon of Tuesday, July 1, 1902.
The 10c UPU card is nicely uprated with the 10c and 20c Adolphe adhesives to pay the special delivery fee. Sadly, today efficient delivery service costs a lot more than three times the price of a UPU-rate postal card, here or anywhere else!
