New York: International Publishers, ca. 1932. 12mo. 182 p. 1st American ed. Very good. 
According to the publisher's buurb, "neither the personages nor deeds of this novel have been 'invented.' They have been taken from the actual events in a Berlin working class street during the May Day barricade battles, which marked the turning point in the class struggle in Germany. This, an outstanding novel of international revolutionary literature, throws a penetrating light on the situation in Germany today"
