Oriel Plas Glyn-y-Weddw is within a listed mansion house

They are just two of the 105 lots on offer at Oriel Plas Glyn-Y-Weddw in Llanbedrog, north Wales, on Sunday.

The cash is needed for the maintenance and upkeep of the gallery, which is housed in a Grade Two listed mansion.

Other lots include holiday cottage lets, jet flights to Ireland and a meal for eight cooked by a top chef.

Helen Williams-Ellis, from the gallery, said it was difficult to say how much money would be raised.

This original Kyffin Williams painting has a reserve price of �25,000

"I am hoping for �40-50,000 and that will go some way toward to the upkeep and costs of the gallery," she said.

"We need to raise substantial cash, and have put a lot of effort to make this a substantial do.

"We have a real cross-section of things - an enormous number of artists have been incredibly generous.

"We are expecting people to bid for lots by phone - we know someone will be bidding on a mobile from Austria."

She said that the original Kyffin Williams oil painting had a reserve price of �25,000, and they were expecting hopeful buyers to travel from as far afield as London for the auction.

Also up for auction are a sculpture by Rosemary Rempe, an original Kyffin Williams watercolour, tea in the House of Commons with Lembit Opik and Si�n Lloyd, lunch for two in the House of Lords with the Welsh assembly presiding officer Dafydd Elis-Thomas and tickets for the Wales-New Zealand rugby clash in November.
