ANTIQUES ROADSHOW host Mark Walberg joins appraiser Beth Szescila for a tour of Bayou Bend in Houston, Texas, the extraordinary museum and gardens that once were home to famed philanthropist and antiques collector Ima Hogg. Following in Miss Ima's footsteps, modern-day collectors arrive at the Reliant Center with impressive finds, including an early 19th-century box desk made by a renowned supplier to the British royal family; a valuable collection of lithographed orange crate labels; and a 1959 replica of artist Edith Parson's early 19th-century Turtle Baby bronze sculpture, valued at $35,000 to $40,000.
