Bill Willingham, the creator of the long-running Vertigo series, Fables, which was recently revived as part of DC's Black Label line of comics, has announced that he is putting the characters into the public domain as a result of years of disputes with DC over his contractual rights to the characters of the series, which is about a group of mythological beings who were exiled from their homelands to go live among humans. Mark Buckingham and Steve Leialoha have been the art team throughout most of the series, but Willingham has been the sole owner of the IP rights to Fables.
