A private collection of more than 1,000 marionettes; an heirloom 18th-century desk whose drawers are stuffed with 300 years of family documents and history

In Dallas, Texas, ANTIQUES ROADSHOW host Mark L. Walberg and appraiser Noel Barrett jump at an offer with no strings attached — a trip to see a private collection of more than 1,000 marionettes. Highlights include a circa 1870 English Victorian oak wall clock; a 1960 John F. Kennedy campaign poster; and an heirloom 18th-century miniature desk whose drawers are stuffed with 300 years of family documents and history, valued at $100,000.
