We've introduced you some of the oddest vintage cameras before, but what if you're in the market for something smaller, perhaps something that could be hidden in a pocket or a cigarette box? Here are some of the great spy cams ever sneak a photograph.

Up top is the Bakelite Coronet Midget box camera with a Taylor-Hobson f10 lens and a 1/30s fixed-speed shutter, introduced in 1935, and produced until 1943.

The ultra-cheap, lightweight and matchbox-sized Midget took six exposures on 16mm rollfilm, and was available in several colours. It was distributed as a prize in cereal boxes.
