Which Looney Tunes are public domain?
As an avid fan of Looney Tunes, I'm curious to know which characters and episodes from the beloved cartoon series are considered public domain? Are there any specific guidelines or criteria that determine which Looney Tunes properties have fallen into the public domain, and are therefore free for anyone to use or reinterpret? Can you provide me with a list of the Looney Tunes characters and episodes that are now considered part of the public domain, or at least give me a general idea of how to go about identifying them?
