A rare typescript of children's story The Little Prince, one of the most translated books ever published, is set to go on sale for $1.25m, reports BBC News.
The typescript - a typed copy of a text - was produced in New York by its author, Antoine de Saint-Exupéry, while in exile from Nazi-occupied France in the 1940s, and is one of three known to be in existence.
The copy contains handwritten notes and sketches by Saint-Exupéry. It will go on sale at the Abu Dhabi Art Festival in the United Arab Emirates in November.
Having the typed manuscript "is an extremely rare event", said Sammy Jay, senior literature specialist from the typescript's seller Peter Harrington Rare Books.
Saint-Exupéry wrote Le Petit Prince, in the original French, for children while living in exile in New York during World War Two. It was published in 1943.
He was an experienced aviator and, after writing the book, he returned to Europe on a reconnaissance mission for the Free French air force fighting Nazi Germany. He disappeared on his last mission while over the Mediterranean, and it is unknown how exactly his plane went down.
The famous work of fiction is about a pilot stranded in a desert who meets a small boy called the Little Prince who is visiting Earth.
Since its publication, The Little Prince has gone on to sell millions of copies around the world.
