Its all happening in this issue! First and foremest, this issue brings us The First Appearance And Origin Of WONDER WOMAN!!! That story continues over in Sensation #1 and a fuller origin was given in Wonder Woman #1.
Doctor Fate dons a new helmet in this issue and two more heroes join the team - Starman and Dr Mid-nite.
Add to that, solo adventures of Hop Horrigan and Starman, plus a cameo appearance by Shiera (Hawkgirl) Sanders and you could be forgiven for thinking that the JSA might not have any time for crime fighting!
