Comicology's The Kingdom Come Companion

Facts (clipped from Wikipedia): In January, 1999, Harbor Press published the first (special) issue of their comics magazine Comicology. The 272-page Comicology: Kingdom Come Companion, edited by Brian Lamken, focused heavily on Kingdom Come, featuring an A-Z of almost everything with extensive illustrations by Ross and various other commentary on the mini-series.

It was the subject of a swift cease-and-desist notice from DC, objecting that the volume "constitute[d] an unauthorized derivative work that infringed upon DC's copyrights, violates their trademark rights, and misappropriates their good will."Lamken acquiesed to the recall, despite protesting that DC had prior knowledge of the project.

It is likely that the similarities between the material contained in the Revelations Volume available only with the purchase of the considerably-more-expensive Graphitti/DC two-volume set contributed to the recall of the Comicology volume.

The recall made the Companion arguably the most difficult Kingdom Come item to find on Ebay and elsewhere.
