Captain America Comics # 1 -- cover - dated March 1941 and on sale December 20, 1940, a year before the attack on Pearl Harbor, but a full year into World War II -- showed the protagonist punching Nazi leader Adolf Hitler; it sold nearly one million copies. While most readers responded favorably to the comic, some took objection. Simon noted, "When the first issue came out we got a lot of... threatening letters and hate mail. Some people really opposed what Cap stood for. '' The threats, which included menacing groups of people loitering out on the street outside of the offices, proved so serious that police protection was posted with New York Mayor Fiorello La Guardia personally contacting Simon and Kirby to give his support.
