When the show was produced, the copyright registration for several episodes was not properly renewed under the old Copyright Act of 1909.

This means you can legally download those specific episodes from the Internet Archive without fear of infringement.
The show centered on the Cleaver family: wise father Ward (Hugh Beaumont), nurturing mother June (Barbara Billingsley), athletic older brother Wally (Tony Dow), and the curious, often mischievous Beaver (Jerry Mathers). Leave It To Beaver Complete Series Internet Archive
