World War II was not only a clash of states, but also a clash of ideologies. Nazi Germany announced the superiority of the "Aryan race" (of course, in the first place were the Germans) over all other races and nations. The Soviet Union opposed the ideology of internationalism and the equality of all peoples. In the United States in those years there was discrimination against blacks, but some publishers considered it their duty to lead an anti-racist campaign .
Publisher George Hecht was a humanist, and promoted his thinking in the magazine "Real comics" (True Comics). In particular, he used his comics to promote anti-racism, which was to resist propaganda of superiority of the "Aryan race", promoted by the Nazis. In September and October 1944 True Comics released a comic "There Are No Master Races", where an attempt was made to explain why all races are equal. We invite you to read this comic.
A good article on True Comics can be found at VCU Libraries. More True Comics can be read at The Digital Comics Museum.
Meanwhile enjoy the "There are no master races" comics!
