Its disguise was simple: it was a plainbox resembling a large and rather heavyparcel or a piece of luggage, with no externallens or controls. When people caught onto the deception, though, designers beganhiding cameras in other objects, rangingfrom hats and books to purses and pocketwatches.

Timers were set to triggerthe cameras when the pigeons were expectedto be flying over their targets. Thatparticular attempt proved impractical, butthe idea behind it did not: aerial photographybecame a staple of World War II.In the mid-twentieth century, a new era ofspying with cameras began under the ColdWar.
