In Milwaukee, Wisconsin, ANTIQUES ROADSHOW host Mark L. Walberg and appraiser Nicholas Lowry peruse the world's largest collection of posters by French lithographer Jules Cheret, best known for his colorful advertisements for the Moulin Rouge. At the Midwest Airlines Center, appraisers get a kick out of the objects arrayed for their evaluation, including a charming 1772 needlework sampler crafted by the youngster who would become renowned clockmaker Aaron Willard's wife; a lovely circa 1890 Japanese bronze sculpture of a peasant woman and baby; and a ruby and diamond bracelet, purchased by the owner's great-grandmother - a German countess - from Austria's Empress Eugenie in the 1890s, with an auction estimate of $30,000 to $ 35,000
