POSTCARD SENT TO A GERMAN SHIP IN ST. THOMAS - POST TREATED

St.Thomas March 20 to S.M.S Panther (German Navy) in St.Thomas harbour - Local ship arrival postmark March 20 1903. Commercial mail rather than philatelic  - message on the reverse. Very rare. 

The German Navy was in St.Thomas due to the Venezuelan blockade - which had just ended.

 

St.Thomas March 21 to S.M.S Panther (German Navy) - no arrival postmark - sealed and not opened. Philatelic.

St.Thomas March 30 to German Naval Flagship “Vineta” - German Consulate - no arrival mark - but sealed and then opened - likely non-philatelic.
Maybe commercial. Inverted frame - Printing 4.
