HARPER'S WEEKLY, New York, Sept. 14, 1901  Unusual that the color front and back wrappers are still present (typically removed), which are quite colorful and decorative. The from notes this is the: "St. Louis Number", site of the Louisiana Purchase Exposition. There is a nice double page centerfold on this event.
Also much coverage of the assassination of President William McKinley with a full front page photo of him. Also inside: "The Shooting of the President" "How New York Received the News" plus more on him.
Additionally articles and photos relating to the Exposition. 
The complete issue in very nice, clean condition.
