I picked this up at Brimfield yesterday, a Whittaker Micro 16 camera, a spy camera. A little bit bigger and a lot heavier than a deck of cards, this camera was made in Los Angeles by Wm. R. Whittaker, LTD of Hollywood. Detectives used it since it would fit in an empty cigarette wrapper, it was easy to hide. It took a 24 exposure, 16mm film cartridge, I found a Flickr page that has some photos from one, pretty cool feel to the images.
