Transportation Postcards

This postcard contains the image of the SS Leviathan.

You can learn even more when you read the back of the postcard:

"S.S. Leviathan. Largest and finest Steamship in existence, containing all the accommodations of the most modern hotels and is practically unsinkable. Length 950 feet. Breath 100 feet. Displacement 58,000 tons. Speed 26 knots. Height from keel to top of mast 297 feet. Accommodations for about 3,700 passengers and crew of 1,200 men. Built in Germany and launched in 1913."

Does this ship remind you of another famous "unsinkable" ship during the same time period?
