In 1973, DC Comics secured the comic book rights to The Shadow, the pulp magazine and radio star of the 1930s and 1940s. Around the same time as his series debuted, DC had The Shadow meet up with Batman. In the story, we learned that The Shadow had been an early inspiration to Bats. They teamed up once more before DC gave up their Shadow license, thus preventing the stories from being reprinted. But for those of us lucky enough to hold on to the originals, we can still thrill to the vigilante who was even scarier (and nuttier) than Batman.
