Upon issuance of the 1901 Yacht Issues, an unknown number of copies were overprinted and distributed to post offices as specimens.
Postmarks of Kiautschou
Upon the printing of the 1905 / 1919 Yacht Issues, a single imperforate sheet was printed of the 2 Cent issue for the archive of the Reichsdruckerei (Reich Printing Works). The sheet remained in the archive until 1997, when it was broken-up and released for public auction.
Following the Japanese capture of Kiautschou in 1914, over 4,600 German POWs were transported to Japan for internment. Altogether, there were six camps: Aonogahara, Kurume, Nagoya, Narashino, Ninoshima and Bandō.
The 1917/1919 Yacht Postal Stationery are similar to other Yacht designs, but feature a vertical line down the middle of the card, with text centered on the vertical line.
In 1900, Kiautschou began using postal stationery of the standard design depicting Kaiser Wilhelm II’s yacht, the Hohenzollern II.
