A copy of The Da Vinci Code book, signed by the stars of the film version while they were in Lincoln last week, is to go on sale for charity.
Dan Brown wrote the Da Vinci Code, signed by the cast and crew
It has the autographs of Tom Hanks, Sir Ian McKellen and director Ron Howard, plus other cast and production crew.
The pages are littered with comments and notes about the film direction.
It is owned by restaurateur Alan Ritson who said: "I understand this is one of only three signatures Tom Hanks gave while he was in the city."
He added: "It is even more valuable for that."
Bookings had been made for three nights at Mr Ritson's Old Bakery Restaurant by the cast and crew of the film. His wife suggested having a copy of the book on hand and asking for autographs in the book.
Filming took place for a week in Lincoln Cathedral
Some of the cast and crew signed it and then took it away with them to pass around the film set the following day.
Both Sir Ian McKellen and director Ron Howard dined in the restaurant.
Mr Ritson said they asked for a discreet corner, but otherwise were treated like other customers.
He said: "We afforded them exactly the same service and quality of food we afford to anyone who comes through our door."
Tom Hanks was due but never arrived as filming ran late one night.
The money will support the Mayor of Lincoln's charity. The signed book will be on view in October when the mayor's charity dinner is hosted at the restaurant.
The book, written by Dan Brown, will be auctioned on an international website when the film is released next year to maximise interest.
The cast were in the city last week and Sister Mary Michael, 61, knelt in prayer outside the cathedral building for 12 hours to object to the filming.
She claimed the film contains heresy.
