On 20 April 1905, a typhoon damaged the Ponape post office. Among the losses were the Ponape canceller and a large number of stamps.
The overprint issues used throughout the German colonies were replaced in 1900/1901 with a standardized design, featuring Kaiser Wilhelm II’s yacht, the Hohenzollern II.
In May 1900, a second printing of Karolinen overprints came into use. This second printing featured the same “Karolinen” overprint, but at a steeper angle (56°) than the earlier printing (48°).
The first stamps produced especially for the German colony in Karolinen were overprinted versions of German Empire issues.
