Behold, in all its gigantic 2500 x 1060 px glory, the oceanliner Cristoforo Columbo from 1955.
This 29,100 ton Italian Line ship provided 703 tourist class, 225 first class, and 320 cabin class cabins.
It’s a Rolf Klep masterpiece, part of a larger LIFE double spread that included an Super-G Constellation in the upper left. I’ve done my best to stitch it together from separate images.
