First edition, first printing, of Rand's final novel, offering her most extensive exposition of her Objectivist philosophical system, "the concept of man as a heroic being, with his own happiness as the moral purpose of his life, with productive achievement as his noblest activity, and reason as his only absolute" (endnote). Its influence on American conservative and libertarian thought continues to be felt. The bold jacket art is by the influential cover designer George Salter (1897-1967).

The page facing the title page has an ownership inscription in purple ink reading, "Property of Roy F. Ginther, S.S. American Ranger, 1958". While serving with that ship, Ginther died in mysterious circumstances in Baltimore Harbour in 1959. Thomas S. Hansen, Classic Book Jackets: The Design Legacy of George Salter, 2005.
