During the mid-century period, high quality cover art was seen as the key to paperback sales, thus many types of books received makeovers. Aussie novelist Ronald McKie's The Survivors is an example. You'd assume it was fiction but it's actually the true story of the Battle of Sunda Strait, which occurred in Indonesia between the islands of Java and Sumatra during World War II and pitted two Aussie cruisers against a major Japanese naval force. During a battle in which the outgunned Aussie ships fared better than could have been reasonably expected, both were sunk. In the aftermath a group of stranded men battled innumerable hazards in an attempt to survive. The book sprang from the handwritten account of an Aussie sailor who spent four years in a Japanese POW camp. He was a friend of McKie's, and when the author read the dairy pages he immediately decided to write a full accounting of the battle. As far as we know nobody ate anyone, but raft rides get pretty rough. The Survivors came out in hardback in 1953, with this Popular Library paperback appearing in 1954.
