Bat-Supe! #53: The Super Sleuth Part 3

After cleverly escaping Herbert Calkins’ test, Superman thinks he’s in the clear. But Calkins isn’t giving up yet. In fact, he’s enlisted a more than willing assistant to help him prove his assertion that Clark Kent and Superman are one and the same! Plus, in today’s Important Message, Billy and all his friends are excited about the Bat-Supers Club, and we’ve got more details on what you’ll get with your membership!
Part 3 of “The Super Sleuth” was originally broadcast on July 24, 1946!
