Second Great War propaganda featuring Superman. Superman was created in 1938 by American Jerry Siegel and Canadian Joe Shuster, and became a popular sensation for children in the United States, Occupied Canada, and even the Confederate States. During the Second Great War, Superman, along with other heroes became important icons in the US, encouraging young people to take part in the war effort by buying war bonds, planting victory gardens, giving away scraps for war material, and more. Throughout the war, he was often depicted fighting Confederate and other Entente spies and saboteurs. This led to him and other heroes being banned by the Freedom Party in the Confederacy and them creating their own variants, most notably
Hyperman. Overall, Superman contributed a great deal to the United States' final victory over the Confederate States.
