The world's most famous crystal ball and The Big Lebowski's omnipresent cardigan are up for bidding at the Hollywood Memorabilia Auction this coming weekend in Beverly Hills.

The crystal ball that tormented Dorothy in The Wizard of Oz was subject to an exhaustive authentication process before it was accepted into the auction at an opening bid of $40,000. Another big ticket item is an early draft of Lucy in the Sky With Diamonds lyrics, written by John Lennon with notes and doodles from Paul McCartney. It opens at $200,000.

The biggest ticket item of all is the orignal, fully functional Chitty Chitty Bang Bang car from the film of the same name. The auction pre-sale estimate is $1,000,000.00

More contemporary pop culture junkies will be interested in the vintage cardigan sweater worn by Jeff Bridges in the cult Coen Brothers film The Big Lebowski.  Although there were three copies of the sweater made for the production, Bridges wore the one Vintage Pendleton Cowichan cardigan for the duration of filming, so that he might delve deeper into the 'Dudeness' required of the role. As of late afternoon on May 12, the bidding was at $11,000, with three days of absentee bidding remaining before the start of the live auction.

Other items of general interest are a collection of Kennedy family portraits shot by Richard Avedon for a story in a 1961 issue of LOOK magazine; and a note Sharon Tate wrote in fountain pen on Chateau Marmont stationery one year before she was brutally murdered by the Manson Family. There are virtually no known artifacts from the short life of the stunning and enigmatic actress. The starting bid is $2,000.

The two-day live auction begins at 11 am on Saturday, at the Saban Theatre, 8440 Wilshire Blvd., Los Angeles, CA.
