This card was first sent in July, 1949, from a train. It is postmarked R.P.O., for railway post office. Addressed to the “Division of American Missions” in Chicago, the sender wrote “I have had some fine meetings. These Danes are interesting people.” A bit of internet sleuthing reveals these correspondents to be Lutherans, which syncs with the Danish reference. Not knowing any Lutherans offhand, I decided to mail it to the Evangelical Lutheran Church of America Archives in Elk Grove, Illinois.
