A painting of the French Riviera by 20th-century American artist Louis Aston Knight; a colorful art deco poster collection of Monte Carlo coquettes; and a stellar collection of perfume bottles.

If the movie business is the heart of Los Angeles, California, then the Academy of Motion Picture Arts and Sciences library is its collective memory, as ANTIQUES ROADSHOW host Mark Walberg learns when he visits this extensive archive of movie memorabilia with appraiser Rudy Franchi. At the Los Angeles Convention Center, the excitement builds as appraisers bestow kudos on such breakout performers as a painting of the French Riviera by 20th-century American artist Louis Aston Knight; a colorful art deco poster collection of Monte Carlo coquettes; and a stellar collection of Bohemian, Venetian and American perfume bottles, including a unique 1912 Lalique example, with a crowd-pleasing value of $30,000 to $40,000.
