In Pittsburgh, host Mark L. Walberg joins appraiser Arlie Sulka at the Carnegie Museum of Art to explore the striking, vibrantly colored vases, bottles and jars made by glass master Maurice Marinot. Highlights include a collection of correspondence between members of the Kennedy family and JFK's former personal secretary; a circa 1928 Art Deco jade sapphire ring; and a 1946 oil painting by Rockwell Kent, along with an inherited letter from the artist, valued at $150,000 to $250,000.
