Received this wonderful card from my friend, Ms. Gordon, U.S.A. She has also fixed ship and boat stamps. Thank you so much Ms. Gordon.
The ship on the card is SS Columbus, built in 1924, by Norddeutscher Lloyd and made her maiden voyage on April 1924. At the time, she was the German merchant marine's largest, fastest ocean liner. She was one of the first liners to have an outside swimming pool installed on her top deck, as well as a platform for night-time dancing.
During the World War II, on 19 December 1939, the British destroyer HMS Hyperion sighted Columbus about 400 miles off the coast of Virginia. The still neutral American heavy cruiser Tuscaloosa was also in the area, and silently observed the two ships. Rather than surrender the ship, her crew scuttled her, and she burned and sank.
