"It's a Small World" is the pilot episode from the iconic American television series Leave It to Beaver (1957–1963). The pilot (originally proposed as Wally and The Beaver) was first televised April 23, 1957, on the syndicated anthology series, Studio 57, without a laugh track nor the series' well known theme song, "The Toy Parade". It never aired as an episode within the series. Following its April 1957 telecast, the episode was subsequently misplaced and was feared lost until a copy was found in a film vault in Illinois. After rediscovery, it was aired as the third-season premiere for the 1980s TBS revival series The New Leave It to Beaver on October 4, 1987, exactly 30 years after the original series officially premiered on CBS. It was televised again in October 2007 as part of TV Land's 50th anniversary celebration of Leave It to Beaver. It was released to DVD in 2005. The series made its CBS debut several months later on October 4, 1957, with the episode, "Beaver Gets 'Spelled". https://en.wikipedia.org/wiki/It%27s_a_Small_World_(Leave_It_to_Beaver)
