This is one of the ever-popular postcards of the S.M.Y. Hohenzollern, which was also known as the S. M. S. Hohenzollern. It shows the royal yacht traveling through a canal and under the Hochbrücke Bridge at Rendsburg. The majestic, white, royal yacht is steaming down the canal’s center. On the reverse, we see that the postcard was mailed by Feldpost in 1918.
