Keychains hiding secret codes

Early 20th-century keychains were used as covert propaganda tools: during World War I and II, governments and private groups distributed metal fob keychains with tiny printed slogans, pictograms, or phonetic codes that doubled as morale-boosters and clandestine signaling devices for resistance networks. Some designs contained microengraved instructions or cipher keys meant to be passed unnoticed on a person’s keys — a practical blend of everyday utility and low-tech espionage.
