and a stand-alone office with an antique walnut desk, an Art Deco lamp by the modernist Irish architect and designer Eileen Gray and a typewriter — an Olivetti Lettera 32 — that once belonged to the novelist Cormac McCarthy. After years of false starts and a second career as a stock trader, Brolin finally became a movie star with his role as an unsuspecting hunter in the Coen brothers’ film adaptation of McCarthy’s 2005 novel, “No Country for Old Men”; he was with the author this past June the night before he died.

Glenn Horowitz, a rare-book dealer who handled the auction for Mr. McCarthy, told The New York Times earlier this week: “When I grasped that some of the most complex, almost otherworldly fiction of the postwar era was composed on such a simple, functional, frail-looking machine, it conferred a sort of talismanic quality to Cormac’s typewriter. It’s as if Mount Rushmore was carved with a Swiss Army knife.”
