Moscow: Vsesoiunaia Spravochnaie Karoteka Ogiz'a, 1934. A complete training course for would-be Comintern Party members, condensing the accumulated wisdom of the first 15 years of Soviet history into a series of flash-cards, each headlined with a revolutionary slogan with explanatory text following. Useful for understanding the myriad shifts in position that accompanied the Third Period and the first years of Stalin's leadership. Likely prepared for distribution at the Comintern's Seventh World Congress of 1935, an event immortalized in Leon Trotsky's scathing (and ultimately fatal) polemic "On the Seventh Congress of the Comintern." 7 copies in OCLC. First edition, illustrated tan cloth clam-shell box (14.5x11.5x6cm), containing 227 loose cards and errata list and 15pp. introductory pamphlet; text is in Russian. Light wear and soil to box; convents Very Good and apparently complete, contents conforming to all catalogued copies listed in OCLC.
