What happens
Clark Kent is desperately searching for a lost letter that could reveal he is Superman. Meanwhile, two pickpockets, Eyebrows and Buster, have obtained the letter and are convinced Kent is Superman after an advertisement offers a reward for its return. Perry White questions Kent about the missing letter, while Bruce Wayne, who is secretly Batman, arrives to help. Wayne warns that anyone testing Kent's identity could be dangerous, and agrees to stay with him to keep watch. Later, the two pickpockets plan a test involving Kent's telephone. This is part five of The Adventures of Superman, first broadcast on 1946-11-29.

Written from the episode itself; it never gives away the ending. Every recording is remastered for the stream: cleaned of rumble, hiss and mains hum (and the old TV whine where we found it), then levelled in two passes to steady broadcast loudness, so one show is never quieter than the next.
