Everyone loves a good spy gadget. From the childhood days of wearing mirrored sunglasses and writing in invisible ink to watching Q’s ridiculous gadgets in James Bond movies, there is a fondness I have for all things ‘spy’. Here in this infographic we go back in history to some of the best real-life spy gadgets. I stress the ‘real life’ aspect because although you won’t find anything quite like James Bond’s underwater-car or wristwatch grapple-guns (though camera pigeons come close to that level of awesome), there are however some pretty incredible stories behind some of these gadgets.
