NYMCO  ,   JAPAN ,  YEN type camera,  1930's
A simple tiny box camera, has a ground-glass and a simple shutter. Is it a toy? Anyway, it seems to be of a good quality- takes the pic. on a small paper/film in holder (insereted into the camera- the camera doesn't open!).
Another nice thing is the back ground glass, when the shutter is pressed to the half:  the picture appears in the ground glass upside-up! A real CAMERA ABSCURA!
