RR Auction will be holding their next Hollywood Auction online, with bidding starting on January 16th and concluding on January 23rd. The catalog, now available online, includes a majority of photos, autographs, scripts, documents, posters and ephemera, though there are original props and costumes as well, mostly from vintage/classic properties. In total, there are over 800 lots.
