More science fiction stuff from DC in April 1947 with All-Star Comics #35. Per Degaton is introduced, who steals a time machine and goes back into the past to prevent Alexander the Great from winning a key battle in order to become ruler of the present-day Earth. As a result, technology starts to disappear in 1947 and the Justice Society have to sort it out and stop Per Degaton from changing history. All in all, a genuinely interesting time travel JSA story with Wonder Woman finally doing more than just being the secretary.
