Yeah, I remember those big, old, folding Polaroid cameras. My uncle had one back in the 1960s and I remember him occasionally taking a photo with it at family gatherings. The key point though is that they folded.
The result was sort of a flat object that was not too bulky when not in use. I think this camera she is holding though doesn't fold up. I recall seeing a used one very similar to this at a shop in Tokyo a few years ago. Quite large and bulky.
