This image provided by the Senator John Heinz History Center in Pittsburgh shows props and sets from the old PBS children's television show "Mister Rogers' Neighborhood," including a model of host Fred Rogers tying his trademark sneakers as he did at the start of every episode. The Heinz History Center is part of the Fred Rogers Trail being promoted by Pennsylvania tourism officials on the 50th anniversary of the show's 1968 launch. A new documentary called "Won't You Be My Neighbor?" has also rekindled interest in Rogers' legacy. (Senator John Heinz History Center via AP)
