London: Faber and Faber, (1957-60). First edition of each of the four volumes comprising his most critically acclaimed work. JUSTINE shows light foxing to page edges but is otherwise near fine in very good or better dust jacket with slight toning to spine, light soiling and tanning and tiny chips at spine tips; BALTHAZAR shows faint spotting along inner hinges but is otherwise bright and fine in very good to near fine dust jacket slightly darkened on spine and toned on edges and with few tiny corner chips; MOUNTOLIVE shows light scattered foxing to page edges and endpapers, otherwise near fine in like dust jacket with touch of rubbing, slight tanning to spine and tips nicked; CLEA shows moderate foxing to endpapers most noticeably on front pastedown but is only lightly foxed on page edges, otherwise bright and fine in near fine dust jacket with touch of light soiling and slightly sunned. Note: Ownership signature of "Harry Blackmer, Paris, 1960" on front pastesdown of CLEA. Presumably the same Blackmer in the 1932 Supreme Court decision that recognized a state's right to retain jurisdiction over its citizens abroad (Blackmer v. United States, 284 U.S. 421). Blackmer was found guilty of contempt for refusing to appear when subpoenaed as a witness for the U.S. in a criminal trial related to the Teapot Dome Scandal. Altogether a very good to near fine set. HIS MOST CRITICALLY ACCLAIMED WORK.
