One of the school books Sir Paul McCartney used as a teenager - featuring a doodle of a man smoking and a teacher's critical comments - is going up for auction.
The Beatle used the exercise book while he was a pupil at the Liverpool Institute High School for Boys, where he was taught English literature by Alan "Dusty" Durband.
A family based in Liverpool, who want to remain anonymous, are putting the item up for sale.
They say they "have had the book for as long as they can remember".
Inside are 22 pages of essays the then student wrote on novels such as Thomas Hardy's The Return Of The Native and John Milton's Paradise Lost.
It also features a doodle of a man smoking on the back cover.
The teacher wrote notes in the margins to the teenager, who would go on to change the course of music history.
"I'd answer the question first before challenging its truth," Mr Durband tells him on page three of the exercise book.
But the teenager, 17 or 18 at the time, showed promise, achieving marks from B- to B++ for his work.
The school book is expected to fetch £10,000.
The auction takes place at 11am today at Omega Auctions in Newton-Le-Willows.
