Warsaw, Wydanwnictwo Ministerstwa Obrony Narodowej, 1961. First edition, first impression. Paperback. Near fine. Precedes the first English-language edition by nearly a decade. Uncommon. One of the finest works in the speculative genre. A highlight of any science fiction collection. Adapted for film three times, the best perhaps being Tarkovsky's 1972 adaptation. Spine tips a touch bumped and rubbed, short tear to the lower edge. Rubbing to the creases, and a reading lean. A wonderful book. In Andrews and Rennison's 100 Must-Read SF Novels [p86].
