Desirable group of eleven different pins, buttons, and badges from the St. Louis 1904 Louisiana Purchase Exposition, of which the Olympic Games were a part. Includes two medal pennant pins, six celluloid pinback buttons (with five for the Exposition and one for its "Missouri Day"), a metal "World's Fair" souvenir badge, and two different "St. Louis, 1904" enameled pins. In overall very good to fine condition.
