In a recent post about the Nedor line of comics, Public Domain Comics scholar Cash Gorman tipped me off to the concept of Orphaned Works. From what I can gather, Orphaned Works are that gray area between Public Domain and material currently under copyright. It's a case where no one seems to know exactly who is the rights holder of the material in question.
That made me think about many of the licensed properties that have shown up in comics over the years. The Wild Wild West comics from long ago have entered into public domain even though the show itself has not.
So what about other licensed comics? Like this classic 1969 Hanna Barbera TV Superheroes comic?
Would this be counted as an Orphan Work?
