Warsaw, Wydanwnictwo Ministerstwa Obrony Narodowej, 1961. First Edition. First Impression. A true first edition, preceding 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 the 1972 adaptation. The book itself is near fine with just the slightest wear to the edges, one closed tear and crease to the rear, upper spine tip and another short closed tear (4mm) to the top of the jacket. Two longer closed tears to the lower spine (25mm & 15mm). A wonderful book. In Andrews and Rennison's 100 Must-Read SF Novels [p86]. [5982, Hyraxia Books].
