A CERAMIC egg painted by JK Rowling is to be auctioned in aid of the Multiple Sclerosis Society Scotland.
The Harry Potter author is among a host of celebrities, including Scots actor Ewan McGregor and painter Elizabeth Blackadder, who have painted their own designs on eggs for a charity auction.
JK Rowling is patron of the MS charity, which she was inspired to become involved in after her mother died from the muscle-wasting disease.
Top auctioneer Alex Meddowes from Sotheby's will attempt to attract the highest bids for the eggs at a charity dinner and auction at the Jam House in Queen Street on Sunday.
Writers Ian Rankin and Alexander McCall Smith, Newsnight presenter Kirsty Wark and First Minister Jack McConnell have also decorated eggs, as have Hibs and Rangers players.
Also up for grabs are an Arsenal shirt signed by the players, an All Blacks ball signed by the Kiwi rugby greats and a top signed by Scotland's own oval ball legend, Gavin Hastings.
The event has been organised by Make Your Mark, a charitable young enterprise company formed by senior pupils at George Heriot's School.
It is hoped the event will raise between 5000 and 10,000 for the society. At least 150 guests are expected to attend.
One of the 14 pupils behind the venture is 17-year-old Andrew Robinson. He said: "We wanted to do something for charity and our original idea was to send out canvasses to artists to decorate.
"But we realised that had been done before and we wanted to do something different that would really stand out. With Easter coming up, we thought it would be a good idea to decorate eggs."
He added: "The MS Society is close to our hearts as not only does it affect more people in Scotland per thousand than anywhere else in the world, but Linda, the mother of one of our group members, Hamish Ross, suffers from the disease."
The youngsters made the eggs themselves, buying the mould for 80 and using the school kiln.
A raffle will also be held, with prizes up for grabs including a year's pass at Knockhill racing circuit near Dunfermline and a night of luxury food at The Jam House.
George Heriot's headmaster Alistair Hector said: "It is a very good cause in aid of the Multiple Sclerosis Society Scotland who themselves have supported the youngsters tremendously."
Admission is 50 per person, including a champagne reception, three-course meal, whisky tasting and live entertainment from The Jam House band. For further information on Sunday's event e-mail firstname.lastname@example.org
