In Atlantic City, New Jersey, ANTIQUES ROADSHOW and appraiser Andy Ourant dip into a discussion of the market for swimsuit-clad, early 20th-century bisque figurines, known as bathing beauties. Program highlights include a collection of Enrico Caruso memorabilia brought by his grandson and a pair of heirloom boxwood and ivory figurines estimated to be worth $50,000 to $75,000, but if confirmed to be 18th-century originals by sculptor Simon Troger, could be worth $400, 000.
