This undated image provided by the Children's Museum of Pittsburgh shows puppets from the old PBS children's television show "Mister Rogers' Neighborhood" on display at the museum. The museum 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 the legacy of the show's host, Fred Rogers. (Children's Museum of Pittsburgh via AP)
