My grandfather sent a postcard postmarked 8 9 13 (I assume that means Aug 9, 1913)from Danzig, Germany. The postcard had a picture of what looked like a public area on a cruise or passenger ship with the words "Danzig Rathaus Diele" printed at the bottom. His written message says that this is the boat he is a mate on and that they will arrive in South Africa Oct. 29.
This is the last my grandmother ever heard from him. How can I identify this ship and could you find any information on it. I am very new at this. Thanks in advance.
