A signed silk tie by Stephen Fry and a flight in a Piper light aircraft are just some of the prizes on offer at an auction of promises.

The fundraiser for WaterAid and the Aylsham High School 2013 prom will take place this Saturday and has been organised by teenager Callum Hall, 15, who attends the school.

Anyone interested in bidding at the free event can view the dozens of lots on www.aylshamhigh.com.

People should arrive at the school at 7pm for a 7.30pm start.

The auctioneer on the night will be Martyn Fox.

Other lots on offer include a one night stay with bed and breakfast at the Red Lion, Cromer; a signed book from Peter Shilton; a meal for two at Constantia Cottage Restaurant in East Runton; a Parker Pen from 10 Downing Street; a shirt worn by Steve McDonald in Coronation Street; a tour for two of BBC Look East and BBC Radio Norfolk; the opportunity to sit in on an afternoon radio programme; and Aylsham Show tickets.

For more information about the auction of promises ring 07788891676 or email prom2013auction@btinternet.com

The event was due to be held on January 18 but was postponed because of the heavy snow.

Callum is on the committee organising this summer's annual prom for year 11 leavers.

This year's prom will be held at Lord and Lady Walpole's Wolterton Hall.

Callum wrote to, phoned, emailed and visited scores of businesses and attractions and asked for items to offer at the auction of promises.

Lots arrived every day, according to the teenager, who is Aylsham high's community champion.

Proceeds from the event will mainly go towards prom funds and a percentage will go towards WaterAid, the charity chosen by the prom committee.

Callum and fellow pupils Phoebe Worrall and Harry Gillingwater all took part in the Cromer Boxing Day dip for the cause and prom committee members have been bag packing in Morrisons supermarket to raise funds.

They are also planning a fundraising fashion show later in the year.

WaterAid is an international non governmental organisation that improves access to safe water, hygiene, and sanitation in the world's poorest countries.
