It was not until the book entered the public domain in 1956 that new editions, either with the original color plates, or new illustrations, proliferated. A revised version of Copelman's artwork was published in a Grosset & Dunlap edition, and Reilly & Lee (formerly Reilly & Britton) published an edition in line with the Oz sequels, which had previously treated "The Land of Oz" as the first Oz book, not having the publication rights to "Wizard", with new illustrations by Dale Ulrey. Ulrey had previously illustrated Jack Snow's "Jaglon and the Tiger-Faries", an expansion of a Baum short story, "The Story of Jaglon," and a 1955 edition of "The Tin Woodman of Oz", though both sold poorly. Later Reilly & Lee editions used Denslow's original illustrations.
