Discover this illustrated vintage poster, depicting a propaganda message in English with a humorous drawing style in black and white accented with red touches. This wall poster features a character holding a puzzle titled "BRITISH PLAN" made of torn pieces, symbolizing an image assembled from "insignificant fragments." Around the character, several speech bubbles express phrases such as "S. Africa’s already there my boy," "seaplanes and destroyers loading up all night," or "shan’t be here tomorrow," highlighting the sensitive and potentially risky nature of sharing confidential information, whether written or spoken.
