South West Africa 1904 Jakalswater Negative Seal on Feldpost

1904 JAKALSWATER NEGATIVE SEAL struck on field postcard to Germany. Displayed are the despatch Deutsch-Südwest-Afrika cds 6/4 (with variety oblique stroke between day & month), Wiesbaden arrival cds 10.05 and unusually in black, the Jakalswater negative sealer applied to Official and Military Mail. Wonderful, fresh, a lovely example.
