This photograph, preserved in a WWII-era China-Burma-India (CBI) Theater collection, depicts a mass outdoor Islamic prayer gathering on a maidan in Calcutta, India — likely Eid prayers, drawing hundreds of worshippers in coordinated rows of prostration. American servicemen stationed in Calcutta as a logistical hub for the CBI Theater often documented local customs and religious life, and this image was preserved in a folder labeled 'folklore,' reflecting wartime curiosity about the cultures encountered far from the front lines.
