here's a good idea!!!!
How about if you were to sell them for a charity? It just so happens that I am involved with a number of charities and I would make sure that the funds were distributed to worthy causes. 'Tis the season for giving, after all.
If this idea does not appeal, Sir Ran is looking for sponsors for his Antartica expedition. In the past he has raised £1.5m for a breast cancer charity. Your donation would receive a personal message from Sir Ran thanking you. If you were to chip in a little more, bringing your total donation to £500, you would receive a framed personal message together with a 'photo of Sir Ran. For £1000, you would be invited to meet him in person at one of Sir Ran's staging posts in the Antartica (obviously travel would have to be at the donor's expense).
