A cultural history of the Grateful Dead illustrated with copyrighted posters commissioned by a legendary concert promoter is protected by the fair use doctrine, a federal appeals court has ruled.

The 2nd U.S. Circuit Court of Appeals ruled in Bill Graham Archives v. Dorling Kindersley Limited, 05-2514, that the use of seven images of concert posters that were displayed in “significantly reduced form” in a 480-page coffee table book about the band did not constitute copyright infringement.
