This was posted earlier by theforce.net. A number of items are up on this auction autographed by none other than Obi-Wan himself, Ewan MacGregor. It will not be cheap, but getting this autograph is not very easy.
Just thought I'd add that this auction benefits Children's Hospice Association of Scotland, Rachel House Appeal. Rachel House is the only Children's hospital in Scotland. All bidding ends September 30th 2002.
