Sinclair tells Kress the proofs of the first one-third of World's End will total 750 pages. He goes on to wish Kress "success with Heubsch," Kress's potential publisher. Benjamin Huebsch, president and editor at Viking Press, saw the potential of Sinclair's World's Endseries. Vanguard Press and Sinclair's longtime publisher, Farrar & Rinehart, passed on the chance to publish the series after lackluster sales of his previous books. Between 1940 and 1953, Viking Press would sell nearly half a million copies of World's End and its ten sequels.
