Sobell House Hospice is offering shoppers the chance to grab some unusual Christmas gifts – including a signed picture of the Prime Minister as a punk rocker.

Rare, weird and wonderful items, which have been donated to the Sobell House charity but deemed too valuable to be sold in its shops, are being auctioned off to raise vital funds for the Oxford hospice.

Lots on offer in the Great Big Online Auction on eBay include: Witney Music Festival posters featuring and signed by the Prime Minister and Witney MP David Cameron Sporting memorabilia signed by stars including boxer Joe Calzaghe An original drawing by Oxford illustrator Korky Paul A giant patchwork quilt created by the Oxford Quilt Group Whisky commemorating the marriage of Charles and Diana A nearly life-size toy pony.

Sobell fundraiser Kevin Game said: “Often these ‘money can’t buy’ type of auctions exclude people who just don’t have that kind of money to spare, so we’re hoping that our range of lots, some with starting prices as low as £4.99, will allow everyone the chance to get involved and support Sobell House.

There are some fabulous things on offer and the auction is already off to a flying start.

“The signed posters of David Cameron are very amusing, and the one of him in a flower power costume seems to be attracting the most bids so far.

“The Winnie the Witch original drawing and book collection illustrated by Korky Paul is also proving very popular and whoever nets this will get a fantastic bargain.

“Butterscotch the pony is also gaining in value all the time.”

Every year Sobell House offers care and support to people and their families affected by terminal illness.

The hospice, on the Churchill Hospital site, costs in the region of £4m a year to run, much of which is raised through its charity.

Mr Game said: “I am always surprised by just how many people across the county benefit from our services.

“And it’s not just people in our hospice – just being able to offer carers the chance of a few hours off with some respite care from our day centre means so much.”

The auction lasts until Monday but eBay users can also get involved by auctioning their own items in aid of Sobell – when uploading an item, they can choose to donate part or all of the proceeds to Sobell House.
