These three arrows on a red field also known as the Anti-Fascist Circle, is the logo of the Iron Front (in German: Eiserne Front), a movement founded in Germany by the Social Democrats and the Workers' Party in 1931 to fight against the rise of Nazis (SPOILER: they didn't make it)
The logo was designed by Sergei Stepanovich Chakhotin, a Russian born in Istanbul who, after graduating in medicine, first became Ivan Pavlov's assistant (yes, the one of the dogs that drool in response to a specific stimulus) and then studied the psychology of Nazi propaganda analyzing the mechanisms of grip on the people and trying, at the same time, to warn the Germans about what was happening but his warnings remained unheeded.
Later he collected the results of this research in the book with the delicate title that leaves nothing to the imagination: "The rape of the masses".
The Story of Sergei Stepanovich Chakhotin deserves a Netflix documentary.
I redesigned the logo in a more modern way and it is available at these links:
