[Banned edition]
The Assassin of Comrade Voykov Before the Polish Court.
Translated from Polish according to the verbatim report of the trial. 
Cover design by N. Sedelnikov.
Moscow-Leningrad: State Publishing House (Gosizdat), 1927.
115, [5] pp. ; 19.5 × 13.5 cm. Good condition. The original publisher's cover is mounted on a custom owner's binding. A 1930s newspaper clipping titled "The Assassin of Cde. Voykov is in Honorable Confinement" is affixed to the endpaper.

This exceptionally rare and historically significant 1927 publication presents the verbatim trial transcript of Boris Koverda, the young White émigré who assassinated Pyotr Voykov, the Soviet Plenipotentiary in Poland. The text provides a deep dive into the political tensions of the late 1920s, documenting the trial in Warsaw following the June 7, 1927 shooting at the central railway station. Voykov, a prominent Bolshevik who had participated in the decision to execute the Romanov imperial family in 1918, was a prime target for anti-Soviet forces. Originally published by the State Publishing House (Gosizdat) with a striking constructivist cover by Nikolai Sedelnikov, the book was subsequently banned in the USSR and relegated to the closed "Spetskhran" archives, only to be returned to general circulation in 1991.
The extreme rarity of this edition is underscored by its absence from major bibliographies, including the second edition of Khachaturov's reference work. This specific copy is preserved in good condition, featuring the original illustrated cover mounted on a later owner's binding, and is uniquely enhanced by a 1930s newspaper clipping titled "The Assassin of Cde. Voykov is in Honorable Confinement" pasted on the endpaper. For bibliophiles, historians of the Russian diaspora, and collectors of suppressed Soviet literature, this volume stands as a crucial primary source capturing a sensational moment of vengeance and international diplomatic crisis.
