"Forever Young" is a celebration of objects for the young and the young at heart. As the show's lovingly preserved appraisals prove, it's not only toys and teddy bears that capture the spirit of youth. Highlights include original art for a Dr. Seuss lunchbox; a child's shoe autographed by Babe Ruth and Lou Gehrig; and a colorful embroidered silk picture, sewn by the owner's great-great-great-aunt at age 15 in 1819, valued at $60,000 to $80,000.
