Episode 322 - Same Bat-Time (Adventures of Superman)

Holy 80th Anniversary, Batman! The Caped Crusader made his first comic book appearance on March 30, 1939, and we're marking the occasion with a complete serialized adventure of Superman co-starring Batman and Robin, the Boy Wonder. It's "The Mystery of the Dead Voice," a tale with ties to young Robin's origin, and it originally aired on the Mutual Network between September 25 and October 16, 1946.
