If you are seeking for info about this camera...it is an instant picture camera which have the picture processed after the picture is taken. The photo is being pulled thro a slit and in it , a chemical pack is being squeezed and spread the processing chemical by means of the roller over the paper surface. It required about 90 seconds for the the picture to be fully developed. After that peel away the piece of backing paper, but can be quite messy. Needs a trash bag stand by to dispose these chemically coated waste.
In th 70s, I'd known some guy who can make quite a sum from this type of camera. One nite easily $500/= Isn't it cool ?
