The sixth-floor storeroom of the Texas School Book Depository in Dallas, where Lee Harvey Oswald, the presumed (by most) assassin of President John F. Kennedy, found a perch above Dealey Plaza, along which Kennedy, Texas governor John Connally, who was wounded, and their wives rode in an open touring car on Nov. 22, 1963. Now called the Sixth Floor Museum, the site is operated by the Dallas County Historical Foundation. Original image from Carol M. Highsmith’s America, Library of Congress collection.
