AJAX (F-21) button camera, USSR (KGB), 1965-1975
The small, lightweight F21 camera was adapted from the German Robot camera in 1948 by the KGB. The F21 was used for surveillance photography; it could take several pictures in quick succession with a spring-driven winder, and it fitted into many concealments, so spies could use it in a wide variety of situations.
This particular AJAX F21 camera is concealed behind a coat button - can you guess which one? The wearer presses a shutter release in their pocket which opens the fake button for the photo.
