Total Eclipse of the Art
A portrait of singer Bonnie Tyler painted by Rolf Harris could fetch £50,000 at auction today.
Cathy Sims, from King's Lynn, recently had the piece valued on the BBC's Antiques Roadshow.
She says her father bought the painting for just £50, 35 years ago.
It is being sold at Barry Hawkins Auctioneers in Downham Market, Norfolk.
Mrs Sims has promised to take her 5-year-old son to Disneyland in Paris if the piece sells.
