In these early tales, the Man of Tomorrows powers were still developing and his foes were often thieves and crooked politicians.
We see a Superman just starting out in his crusade against crime. It's interesting to see that the police doesn't recognize him and shoots at him thinking him a dangerous vigilante. Superman generally goes against common crooks in those days and he's far less powerful then - although this volume shows us the first time he "float in the air" rather than merely "leaping great heights" - he still can't fly like we are used to yet.
This volume also reproduces all the original ads, prose stories and covers thus giving the reader an authentic Golden Age reading experience.
