I read somewhere that they were intended to be carried in pocket of a particular type of overcoat that was popular at the time, where the pocket was bizarrely large. I've got some Kodak "pockets" that I can't even fit in the microwave (not that I would do such a foolish thing, of course...). Nice set up you have here. Is it missing it's little stand? (see on the underside of the door - there should be a small metal rectangle, usually says "Kodak" on it - if you flip it out, it will level the camera out) - I see the side-stand is there - the little metal thing at the left corner - if you flip it out to the side it helps stand the camera while taking landscape shots.
Nice set-up.I'm not crazy about the lighting which looks rather flat. There are too many glares, especially in the velvet at the bottom. I suggest lighting from the side to add more drama and contrast. This looks somewhat literal to me.
I like the idea of the composition. I think the camera and the manual being almost parallel to each other takes away from the "random" placement though.
