first edition, portrait frontispiece, tissue guard (browned and torn at inner margin), light browning to endpapers, spine slightly browned, spine ends and corners a little bumped, sm.4to, 1920. The most important book of poetry from the first world war. The power of Owen s poetry is as significant today as it was when first written, under the encouragement of Siegfried Sassoon (who wrote the introduction to this posthumously published collection), in the trenches of Flanders, mostly in 1917 and 1918. Owen was killed one week before the armistice was signed in 1918.
