In Orlando, Florida, ANTIQUES ROADSHOW host Mark L. Walberg and appraiser Ken Farmer visit the Mennello Museum of Art to see works by curmudgeonly St. Augustine folk artist Earl Cunningham. At the Orange County Convention Center, friendly throngs of guests share tales and treasures, including a valuable circa 1835 Regency-style etagere bought at a yard sale for $20; an animator's plaster model of Geppetto, created for the Disney movie Pinocchio in 1940; and a painting by Fern Coppedge - of the renowned early 20th-century Pennsylvania Impressionist school - given to the owner's grandfather in lieu of medical services and estimated to be worth $120,000 to $ 200,000.
