I saved for weeks and weeks to order a small "Spy Camera" out of the back of a comic book when I was 9 years old. It looked like a tiny SLR made of tin with only a shutter trip and a film winder. It came with one roll of what I now recognize as Minox film wrapped in foil. The plan was take your pics, send in film, receive your prints. Waiting for the prints seemed an eternity. Unfortunately, there were limited instructions. I received six very faint images. Nothing was recognizable and I couldn't remember what I had shot. The film had barely been exposed. Of course at 9 with no photography exprience I figured I'd been ripped off. I never reordered film.
Cest le vis, however you spell that.
