This photograph forms part of a group that is believed to have belonged to Earl Thomas Crain (1907-1989), an American foreign service officer who was stationed in Iran from 1935. The group of photographs are believed to have been originally acquired by the father of Crain’s wife, Elizabeth Agnes Hildebrand, who was an honorary council for Switzerland in Iran after the first world war.
