Radio hidden in a book. This was commonly done in World War II to hide radios from the German occupiers.
Concealment devices or diversion safes are used to hide things for the purpose of secrecy or security. They are made from an ordinary household object such as a book, a soda can, a candle, a can, or something as small as a coin. The idea is that such an inconspicuous object would not be expected to contain anything of worth.[1]
Examples in espionage include dead drop spikes for transferring items to other people, and hollowed-out coins or hollowed out teeth for concealing something - such as microfilm or a suicide pill. Examples in smuggling include suitcases with false bottoms for hiding contraband.
During World War II MI9 was responsible for creating many concealment devices for "escape aids" to assist prisoners of war to escape.
