From Russian photoblog PhotoShtab.ru comes these great pictures of Cold War-era miniature gadgets that KGB spies and others used to monitor, smuggle, and kill (via RussiaEnglish).

Seeing as we have just seen the new adaptation of John Le Carre's Tinker Tailor Soldier Spy, these photos are a another great reminder of how paranoid and insane that whole 'Cold War' period was.
