In honor of Batman's 75th anniversary, we present a bonus podcast featuring some of the Caped Crusader's radio adventures. We'll hear Batman and Robin co-starring on The Adventures of Superman, as they team up with the Man of Steel to save Lois Lane from a murder charge. It all happens in the thrilling conclusion to "Dr. Bly's Confidence Gang," originally aired on Mutual between September 19 and September 21, 1945.
