Papers of Lobeck while he was in Paris as Assistant to the Chief Cartographer of the American Commission to Negotiate Peace. Included are memorabilia, some correspondence, several docuements, and some photographs. The correspondence consists of his letters of appointment from Robert Lansing, Secretary of State, and his postcards to his wife, Bertha Merrill Lobeck, who later joined him in Paris. There are official documents such as passports, Commission memoranda, identification cards, and passes. Of particular interest are sixteen photographs of persons and places in France, and one drawing and one caricature of Lobeck that he sketched. The collection, however, is chiefly memorabilia of Lobeck's crossing the Atlantic on the U.S.S. George Washington with the members of the Commission; over 700 picture postcards, with no messages, of the Lobeck's travels in France, Spain, Great Britain, and other European countries; railway, subway, and bus maps, schedules, and tickets; tourist maps; hotel and restaurant receipts and menus; money; ration coupons; and theater programs.
