This image shows the first diesel-powered trans-Atlantic passenger ship, the M. S. Gripsholm, which travelled between Gothenburg and New York City between 1924 and the 1960s.
The description on the back states:
SWEDISH AMERICAN LINE – GOTHENBURG DIRECT NEW YORK
REGULAR CALLS AT COPENHAGEN, BREMERHAVEN AND HALIFAX
–It was one of two ships of the same name which were owned by the Swedish-American Line. This one was used to transport expatriates back after World War 2 and to repatriate European prisoners from camps in the United States.
This card was used and is dated 5 June 1953, one year before the Gripsholm was sold off and renamed the M.S. Berlin.
