Rare pair of badges from the collection of Secret Service agent Paul M. Hart, who worked as part of Franklin D. Roosevelt's detail during his 1936 cruise to South America; the voyage culminated in the Inter-American Conference for the Maintenance of Peace held at Buenos Aires, Argentina. Includes one badge with a golden Argentine 'Sol de Mayo' emblem backed by a light blue-and-white rosette ribbon, 2.25″ in diameter; and one featuring Brazil's coat of arms with red-and-white ribbon below, measuring 3″ long, with a letter on "Policia Civil do Districto Federal" letterhead, in full (spelling retained): "Notice: The badge enclosed in this envelope serves to identify the bearer as a member of the Secret Service of the United States of Ameria, acting as a scort of President Franklin D. Roosevelt, to whom is allowed admittance to all the places guarded by the police. The badge should be worn in the bottonhole or in any conspicuous place, so that all facilities may be rendered to the persons who carry the same." Also includes two original glossy candid photographs of FDR on board the USS Indianapolis and five blank "Trip of the President" luggage tags. In overall fine condition.
