League of Justice (1,2) two books

Justice League of America #1 (1960) features the team's first solo series, where the Flash must rescue his teammates from the mind-controlling alien dictator Despero, making his debut appearance. The villain, from Kalanor, traps the heroes in "The World of No Return!" before honorary member Snapper Carr ultimately defeats him. Notably, the issue number appears only on the interior insignia, and the cover does not prominently feature Superman or Batman, making it a unique piece for collectors.
