Author of Peter Pan, James M. Barrie died in 1937. Under old copyright law, copyright would have normally expired in 1987, fifty years after the death of the author.

A recent congressional act extending copyrights by 20 years in the US would take that to 2007. However, this math is irrelevant, say the owners of the copyright.

As the owner is not, as one would have expected, Barrie’s descendents.
Apparently Barrie turned the copyright over to a hospital for children in 1929, and an act of British Parliament awarded the hospital the copyright inperpetuity.

A Canadian author recently wrote a sequel, and is challenging this notion.
