Philadelphia, Pennsylvania, has the distinction of being one of the stops in ROADSHOW's first season, taped in 1996. Flash forward a decade and ROADSHOW is back "where it all began" for the popular PBS series, as well as for the United States. Host Mark L. Walberg kicks off the show with a visit to a Philadelphia landmark - the Philadelphia Art Museum. The museum's collection is so large and diverse it takes eight ROADSHOW experts to do it justice. At the Pennsylvania Convention Center, nearly 70 experts offer their opinions of the approximately 10,000 objects brought for appraisal, including a rare 18th-century Pennsylvania spice cupboard used to collect birds egg specimens; a very valuable mid-17th-century needlework piece bought at auction by a savvy collector for next to nothing; and an early 20th-century nicotine stained oil painting by noted Pennsylvania impressionist George Sotter - banished to a flooded basement by the owner - valued at $120,000 to $180,000.
