One woman went to the Rotary Monster Book Fair to find a children's book she remembered from her childhood - and she found the exact book.
Thirty years later it still had her name in it and she took it home all over again, Rotary Club of Whanganui president Stephen Lace said.
The book fair is the club's biggest fundraiser and usually happens once a year.
Across seven days, the club hopes to make $25,000 by selling donated books, CDs, records and puzzles.
"The book fairs have been a wonderful way of giving the Rotary a financial foundation to work from," member Shirley McDouall said.
