Bonham’s has a dazzling array of Hollywood treasures for sale in their latest auction, including Mitzi Gaynor’s costume collection, artifacts from “Gone With the Wind” (you can get an annotated screenplay, costume sketch, Scarlett’s necklace, Rhett’s vest, or even Margaret Mitchell’s contract with MGM!), and the bodice from Theda Bara’s “Cleopatra” costume! There’s an “Adventures of Robin Hood” book signed by the cast, Paul Henreid’s jacket from “Casablanca,” a dress worn by Barbara Stanwyck and Teresa Wright in two different films, a vest worn by Bob Hope in “The Princess and the Pirate,” and a prop poster for “Springtime for Hitler” from “The Producers.” There’s even a pair of Darth Vader gloves from the original “Star Wars” (now known as “A New Hope”).
