Vef Minox Subminiature espionage camera
The Vef Riga is the first and the smallest subminiature camera ever sold commercially by Minox. It dates back to before World War II and was in production from 1937 to 1943.
The Minox was used by both Axis and Allied intelligence agents during World War II. Later versions were used well into the 1980s. The Soviet spy John A. Walker Jr., whose actions against the US Navy cryptography programs represent some of the most compromising intelligence actions against the United States during the Cold War era, used a Minox C to photograph documents and ciphers.
