Red, white, and blue single poster stamp or sticker issued to promote a boycott of Hitler. It depicts a snarling Nazi dog barred from entering a chained gate marked brotherhood of man, guarded by an American eagle. After Hitler came to power in Germany in January 1933, several organizations in the United States sponsored campaigns urging people to not buy or support Nazi related. Among the groups supporting boycotts of Nazi Germany were the American League for the Defense of Jewish Rights, the Non-Sectarian Anti-Nazi League to Champion Human Rights, and the Joint Boycott Council.
