Sir Michael Caine is selling mementoes from his film career and paintings from his personal collection as he downsizes with a new home. The Oscar-winning actor, 88, and his wife Shakira have put film posters, furniture, including his desk, and artworks by Marc Chagall and LS Lowry up for sale at Bonhams auction house. Caine's Rolex wristwatch is estimated to sell for as much as £12,000 ($16,000), while two pairs of his famous spectacles, being sold together, could fetch up to £1,200. A director's chair from the 1971 crime film <i>Get Carter</i>, in which Caine starred as gangster Jack Carter, has an upper estimate of £1,200 ($1,600). Other items from his seven-decade screen career include a poster for the 1966 film <i>Alfie</i> (£500-£800), which earned him an Oscar nomination for best actor, and a two-piece poster for <i>Zulu</i> made for the Italian market (£1,500-£2,000). From his art collection, Caine is selling <i>Peel Park</i> by LS Lowry, a black chalk and pastel work from 1920, which has an upper estimate of £18,000. <i>Les Amoureux Dans L'Arbre</i> by Marc Chagall, meanwhile, could sell for as much as £50,000. "It's going to be quite a wrench to part with so many treasured parts of my life and career, but it's the right time to be moving on," Caine said. "I hope these mementoes will give their new owners as much pleasure as they have given us." Last year he dismissed reports he had retired from acting, after he said in an interview that comedy-drama <i>Best Sellers</i> would be his "last film". "Sir Michael Caine is a cinema legend internationally and a national treasure here in the UK," said Bonhams' director of house sales and collections, Charlie Thomas. "I know the Sir Michael Caine Collection sale will excite great interest among collectors and film fans alike." Lincoln Townley's portrait of Sir Michael is also due to be sold, with an upper estimate of £15,000. Proceeds from it will go to the National Society for the Prevention of Cruelty to Children. "Sir Michael Caine is a former patron and longstanding supporter of the NSPCC," said Sir Peter Wanless, chief executive of the charity. "We are touched and extremely grateful he has chosen to donate all the proceeds raised from the sale of this fantastic portrait of him to such an important cause. "We also thank the artist, Lincoln Townley, and Bonhams for waiving their vendor's commission from this upcoming auction. "Fingers crossed the painting is sold for a price that is befitting of Sir Michael's considerable talents and generosity." - <i>Sir Michael Caine: The Personal Collection</i> will take place at Bonhams on Wednesday, March 2.
