This card is a bit of a mystery. Walter Kahl sent this from Cottbus to Francis H. Sweet, Company E 15th Infantry in the Philippines in 1913. Cottbus is a city in northern Germany, located about 78 miles southeast of Berlin. The card has the stamp on the front, which was fairly typical in France, but unusual in Germany.
The message itself is also unusual. Well, actually there isn't a message, just a name and address and "Hedwig" below that. Hedwig is a female name in German. So, whether it's a code name of some kind or another way of relaying a message, I can't say for sure. In any case, the card has many date stamps, starting with the cancellation date on October 3rd, 1913 and ending with a received stamp of November 14th, 1913. There are several other handwritten notations on the card. It's all very mysterious.
