In the summer of 2015, Gil Wells found his 79-year-old godmother with a plastic sleeve holding two small sheets of White House notepaper. Wells pulled them out, turned one sheet over and stopped cold. “I saw ‘Nov. 22’ and ‘pink and navy Chanel suit,’” he recalled. The handwriting was Jacqueline Kennedy’s, and the notes were a list she had drawn up before the fateful trip to Dallas in November 1963. Since March 2016, they have been housed at the John F. Kennedy Presidential Library and Museum in Boston.
