German WWI / WKI Kriegsmarine Navy Marineschiffspost from navigation officer Ernst Wieblitz of the the SMS Dresden, part of Graf Spee's ill-fated squadron, interned in Chile on Insel Quirinquina. (See the wikipedia articale on him). Datelined from Quirinquina and sent back to a doctor relative (father?). A rare piece of Graf Spee's journey from one of the principle actors.
