Bonhams and Turner Classic Movies have joined together again for another auction of classic Hollywood memorabilia, with treasures from the golden age of movie-making, including the piano Sam plays “As Time Goes By” on in “Casablanca,” the cowardly lion’s costume from “The Wizard of Oz,” and scripts for “It Happened One Night,” “Dr. Strangelove,” and “The Lady Eve.” There’s a script of “David Copperfield” signed by the whole cast and the script supervisor’s copy of “To Kill a Mockingbird” with a small photo of the ham costume worn by Scout on the cover. There are dresses worn onscreen by Deborah Kerr, Grace Kelly, Rita Hayworth, and Maureen O’Hara. You can bid on Moe Howard’s watch, Laurel’s and Hardy’s suits, or a suit worn by Jerry Lewis in “The Nutty Professor.” Even if you are not a collector, it is still a lot of fun to page through the catalogue.
