See India - Kedarnath, Source of the Sacred Ganges (1930's)
G. Tait
Kedarnath is a Hindu temple dedicated to the god Shiva located in the Himalayas to the northeast of Delhi and close to the Tibetan border. It is inaccessible through out much of the year and lies on the banks of one of the highest tributaries of the Ganges, hence the identification on the poster of Kedarnath being the source of the Ganges.
