Octopus Publishing Group has signed world rights in Churchill: The Life - In His Own Words and Pictures.
The illustrated history of the prime minister's life draws on unique archive resources, in association with Churchill Heritage Ltd, and written by historian Max Arthur.
Editorial director Trevor Davies signed rights in a deal with Gordon Wise at Curtis Brown.
Davies said: "'This will be an exciting and original take on Winston Churchill's life. We will be delving into the Churchill Archives in Cambridge, which houses a treasure-trove of artefacts, documents and images. The illustrated content will include items such as drafts of speeches, correspondence with kings and presidents, menu cards signed by 'The Big Three', and Churchill’s unique doctor’s prescription that permitted him to drink during American Prohibition. All the objects have their own story to tell, but brought together they will give a complete and fascinating portrait of Britain's greatest son."
He added: "We also hope to feature such family treasures as his honorary citizenship of the United States signed by JFK, and his Nobel prize. There will be original quotes from Winston, his wife Clementine and other family members to embellish Max's words, as well as selections from the family's rarely-seen photograph albums to make the book a comprehensive study."
The book will be published in September 2016, to mark the conclusion of the Churchill 2015 year - the 50th anniversary of his death, the 65th anniversary of his first premiership and the Battle of Britain, and the 70th anniversary of the end of the Second World War. It will be released as a £25 hardback.
