I'm sure this book will be on the Christmas list of lots of Lennon and Beatles fans.  Yoko has come out to clarify she did "sell any rights" like this article states, either way it should be a good read for fans.

Yoko Ono has sold the rights to a collection of letters penned by John Lennon. Ono was persuaded to publish the letters by Hunter Davies, the Beatles' biographer.

The book will be comprised of over 150 letters written over the course of Lennon's life, including notes to record companies and newspapers, several drawings and a letter to an eight-year-old boy. According to Alan Samson of Orion, a majority of the letters and drawings in the book have not been seen by the public.
