Before ANTIQUES ROADSHOW can pack up its trunk and wave aloha to Honolulu, Hawaii, host Mark L. Walberg and appraiser Anthony Slayter-Ralph pay a visit to Shangri La, home of the late heiress Doris Duke and one of Hawaii's most architecturally significant homes. At the Hawai'i Convention Center, guests hope for fame and fortune, too, with a wide assortment of objects to be appraised, including a first edition copy of Jack London's Call of the Wild; a 1915 Hawaiian flag quilt, bearing the coat of arms of King Kamehameha; and a violin and bow purchased for the owner's aunt in 1921 and kept in storage for the last 40 years. Although it's accompanied by a bill of sale claiming the instrument is a valuable Camilli from 1737, the violin actually is a fine forgery - so fine that the pair still is valued at $12,000-$15,000 at auction.
