in the savage time the justice league went back in time to fight against vandal savage in world war 2 during D-day while in legends john stewert says something about how he grew up reading about a in dcau fictional superhero tema called the justice guild who character wise were obviouse homages to the golden age era jsa green lantern, the flash , the atom, black canary, wild cat, and batman just my thoughts people but in universe wise it is entirely possible that the justice league inspired the creation of the fictional justice guild comic book when the justice league went back in time to fight vandal savage in ww 2 thoughts people?
doubtful. In Legends it was explained that the Justice Guild was a real parallel world. The people who wrote and drew the comic were genetically tuned to that world's wave length. What they thought was just imagination was the real exploits..
