'Yesterday's enemy is today's friend' (US leaflet 18-J-1 to Japanese troops)
A Japanese-language leaflet with a large calligraphic title, 'Yesterday's enemy is today's friend', over a photograph of shirtless and hatted prisoners crowded round a pool table under a thatched roof, their eyes masked. Vertical text on the right cites three articles of the 1929 Geneva convention on prisoners of war. The tell is a single benign camp scene offered as the whole picture of captivity, with the choice to surrender left implicit.
