Not a real camera (sadly), but this Vintage Camera Pencil Sharpener is certainly a head-turner, not to mention a useful thing too.
If you hadn't guessed, this is based on a twin-lens reflex camera, but is actually something for the office, keeping your pencil sharp to your personal choice (via an 'adjustable sharpness knob'), with a pull-out tray for shavings.
Available online, it sells for $12.95.
