From 1989 to 1992, DC published a new Shadow comic book series, "The Shadow Strikes!", written by Gerard Jones and Eduardo Barreto. This series was set in the 1930s and returned The Shadow to his pulp origins. During its run, it featured The Shadow's first-ever team-up with Doc Savage, another popular hero of the pulp magazine era. The two characters appeared together in a four-issue story that crossed back and forth between each character's DC comic book series. "The Shadow Strikes" often led The Shadow into encounters with well-known celebrities of the 1930s, such as Albert Einstein, Amelia Earhart, Charles Lindbergh, union organizer John L. Lewis, and Chicago gangsters Frank Nitti and Jake Guzik. In issue #7, The Shadow meets a radio announcer named Grover Mills, a character based on the young Orson Welles, who has been impersonating The Shadow on the radio. The character's name is taken from Grover's Mill, New Jersey, the name of the small town where the Martians land in Welles's 1938 radio broadcast of "The War of the Worlds." When Shadow rights holder Condé Nast increased its licensing fee, DC concluded the series after 31 issues and one "Annual"; it became the longest-running Shadow comic book series since Street & Smith's original 1940s series.
