Juvenile Jury - 1953, Hosted by Jack Barry
This has been uploaded before, but hopefully this upload has better picture quality....if it doesn't, I promise to delete it. A 1950s panel show featuring young kids answering questions and problems sent in to the show. Yes, this is the infamous episode where a child reveals she has been given the questions in advance. There are perhaps 3 or so other surviving episodes...I'd love to see them.
