Bonhams and TCM are proud to announce their third annual movie memorabilia auction, Treasures from the Dream Factory, to be held in New York on November 23.  Following on the success of the 2013 and 2014 auctions-where the Maltese Falcon sold for $4.2 million and Sam's piano from Rick's Café in Casablanca sold for $3.2 million-this year's auction features such high points as the dress worn by Judy Garland in The Wizard of Oz, a selection of screen-worn gowns of Marilyn Monroe, and Herman Mankiewicz's personal Rosebud sled.
