Superb pair of fancy "shield" killers on cover from St. Louis to Iowa City, IA

Boldly struck killers and CDS. Sent to Newton R. Parvin, son of Theodore S. Parvin, first Governor of the Iowa Territory. By 1872, Newton joined his father in the office of the Masonic Grand Secretary in Iowa City, starting as a clerk and later becoming Deputy Grand Secretary. You would be hard-pressed to find better shield killers or a St. Louis CDS as nice as these anywhere.
