This set of images of Korea was acquired by the American
Geographical Society from Shannon McCune (1913-1993), Professor
of Geography and Asian Studies. The pictures were taken between
1938 and 1939 during McCune's stay in Korea when he conducted
research for his doctoral dissertation "Climatic Regions of
Tyosen (Korea)". In his captions McCune uses Japanese names for
Korean places, e.g. Tyosen (Korea), Heizyo (Pyongyang), or
Keizyo (Seoul). For more information, please see McCune,
Shannon. Climatic Regions of Korea and Their Economy.
