# 秘密戰ヲ防ゲ (Guard Against Secret Warfare), Japanese home-front counterintelligence poster

A poster under the title 'Guard against secret warfare' shows a Rising Sun fan turning away a flurry of paper slips, each carrying one word: hoarding, individualism, communism, hedonism, grievance and discontent, strikes, rumour, worship of America and Britain. The slips treat these attitudes and behaviours as the weapons of a hidden enemy, so the labels do the work and no spy or act of spying is shown.

Read from a 500-px reproduction. The title and nine of the eleven slips are clear. The white slip at upper left and the fan's own characters are distorted by the fan's curve and are not guessed; the slip at lower left is a best reading and marked as such. Vertical slip text is given in reading order.
